Pull data from various APIs using a Python script on Amazon ECS, we do. Poller runs, hits the API, retrieves data, and pushes it to Amazon Kinesis.

Adding Kafka push, increased to 2.5 seconds, it did. Not acceptable for large-scale data, this was. \n\nOptimize, we did, by batching logs. Instead of pushing logs one by one, collect them in a list, we did. Push all logs in a batch, we do. Reduced processing time to 400 milliseconds, we have.

At GoFrugal Technologies, I have worked with two retail based product, inventory control application and price checker applications. Inventory control application which has four main features which is mainly used for retail based products. For example, if you take a supermarket as an example, they will do a stock counting on daily basis. So they will make use of the stop taking feature and will count the stock on daily basis. And there is also another feature called good received. So whenever the supermarket receives the goods from the supplier, they will make a GRN. So they will make use of that feature. So another feature is called stock picking. So whenever the customers, the supermarket owner or any retail based owners will get an order from the end customer, they will do a stock picking. So they will use the stock picking feature and pick the stock from the supermarket or their business and they will move to the billing area. From the billing area to, they will move to the end customer. And there will another feature called the stock refilling. Stock refilling is, features always ensure that the rack is always filled with the items. So whenever the end customer goes to the supermarket, they should not feel like there is no items. The stock refill ensure that the rack is always filled. So this is the stock management inventory control application. So I have done another application called price checker application. Price checker application is used for the, which will be like, which is for a tab, tab. The tab will be placed in the supermarket. Basically, whenever the end customer comes to the supermarket, and they just want to check the price and discounts and offers of that any item, they can scan the item and they can, they can get to know about that. And they can also use to check if they have any loyalty card with them. So they can also check the loyalty points and when it gets expired and how that\'s reading point will be there. And that will be present in the price checker application. I have, during my tenure at HTC Global Services, I have worked with two products. One is Harman service support application and another one is a Penske supply chain insight. Harman service support application, which is basically having a door installations instruction will be there, door installation videos will be there. And there will be a circuit diagram to provide to the service persons. They can make use of that application, they can provide the best service to that end customer. So and another application is called Penske. The Penske is doing a logistic and transportation business. And they just want to track the loads and orders and orders of those companies using that application. So they can make use of this application, they can able to track the loads and orders and where is it going and how many orders per stops. And they can also watch it some of the company\'s orders and loads and they can make use of that. And in this currently I\'m working in Penske supply chain insight application. And in this application, we have the Google map and here map integration. And in this using this Google map and here map, we ensure that the customer can get to know about where the load and order is exactly going and in which process whether it is going on on time or late and that and all they can get to know also they can also track the warehouse inbound and outbound items related things.

So we have to maintain the thread accordingly, also we have to specifically for the short term use we have to use the weak references of the resources and weak references of the objects and we have to aware about the context that we have used in our application. So whenever we need we have to use the activity context instead of the application concept. So because the lifetime will be different. So another thing is like we have to done the resource optimization, we can done resource optimization by like by using images like by using the vector image instead of the bitmap and we can reduce the overdraw in layouts and we can optimize the layout in by reducing the overdraw and we can also we can also reduce the memory leak if there is any and we have to we have to include techniques like lazy loadings and we have to include lazy loading related things and if there is and I always used to check the CP Android app CP usage memory usage and network usage and it will track that using the Android profiler and so if using the Android profiler we will get to know about it and we will track that and if there is if there is a want to perform any optimization we can done in development itself and so for the network related things we can catch the response and we can catch the response and request and we can optimize the network call we can reduce the unnecessary network call and we can catch the image response if we are using the glide so that that thing we can done.\n','My approach to performance optimization and resource management is crucial for handling background processing efficiently.

Identifying and fixing memory leaks is a priority, and I implement techniques like lazy loading.\n\nI use the Android Profiler to monitor CPU, memory, and network usage, tracking performance metrics throughout development. To optimize network performance, I cache responses and minimize unnecessary calls, and I rely on Glide for efficient image loading and caching.\n\nFor example, in the inventory control application, I optimized performance by moving background tasks to background threads, implementing vector images and lazy loading, and identifying and fixing memory leaks.

So, if you see about the project experience which I have. So, initially in the first 6 years I am part of mobile apping development in Android based platform in a company called TCS. So, where our project focus was to deliver a mobile application for banking customers. Where the customer can use that application to do all the banking transaction like fund transfer. We can create a recurring deposit or fixed deposit. All the banking related transaction can be done through the mobile application. So, I was part of the team and I was leading the team for 5 members Android team. So, basically like since it\'s a banking application. So, we have to be very concerned about the security things. Since it deals with the transactions and the amount. So, we have to be very careful on sending the data between the mobile and the backend systems. So, we used to do so many things for confirming all the security precautions. Like we\'ll be using encryption decryption logics and hashing logics for the passwords. And we\'ll be pinning the certificates while making an API call. And we\'ll be enabling ProGuard all those stops in mobile app code. So, that even if the hacker or reverse engineer our application. It\'s difficult to find out our mobile app code related stuffs. So, next project experience what I have is on Ford Motor Company. So, it\'s about 2.5 years I\'m working in this application. So, it\'s a connected vehicle application and in automotive domain. So, we are working in application where we can use all the connector services of the vehicle. Like we can start the vehicle. We can precondition the vehicle. We can switch on the AC before getting to it a car. We can schedule that departure time like the vehicle will be ready with having air condition on in a scheduled time. And we\'ll be having petrol diesel variants as well as the hybrid vehicles like electric vehicles. We\'ll be providing option to do charging. And to find the charging stations nearby based on the mobile location as well as the vehicle location. And we\'ll have a service related things in our application like user can enter their service records. Or if they are doing in any authorized service center. The data will be provided automatically once they have completed the service. Similarly, we have like roadside assistance, collision assistance. So, if in case of any emergency, they can raise a request for roadside assistance. Which the back-end team will be addressing it based on like we\'ll be providing all the user interface for the customer to proceed with the roadside assistance. The major part which will be I\'ll be working on like I was working in roadside assistance and vehicle alerts. Something like if there is any alerts in the vehicle, we\'ll be showing up in our mobile applications like the oil life is very low or if the fuel is very low. Or if the door is opened and the car starts to move, we\'ll give an alert notification to the mobile app. Similarly, we have a stolen services subscription in our mobile app. Like if there is a chance of the vehicle got stolen, we can raise a concern from our mobile app so that car will get the live location of the car. So, these are the things which I\'m working in the current company. Thank you.\n','I have over eight years of experience in Android development.

So all those things we will be considering when we develop an app. And so basically, like we will be following solid principles, like so how the app has to be for easy maintainable code and flexibility and like it\'s smaller release and lightly loosely coupled so that if there is any change in future future, if there is any change in future, like don\'t we don\'t want to make so many code changes and which affects so many files. So we\'ll make the code loosely coupled and like will be it\'s since it\'s a mobile app. So we\'ll be developing over the Android application. So Android OS and so we will be using Kotlin language for it.\n','At Ford Motor Company, we adopt a thoughtful approach to developing the Android platform, particularly in relation to system services and lower-level layers. \n\nWe prioritize executing all operations on the appropriate threads. For example, API calls and database operations are managed in background threads to prevent blocking the main thread, which is dedicated to UI updates. This strategy guarantees a smooth user experience and optimal performance.\n\nWe also adhere to SOLID principles to maintain a clean, flexible, and maintainable codebase. By keeping our code loosely coupled, we can implement changes and updates with minimal impact on the overall system. This practice is essential for preserving the integrity and functionality of the application over time.\n\nIn terms of system services, we collaborate closely with Android\'s architecture to fully leverage its capabilities. This includes utilizing Kotlin for development, which provides a robust and modern language for Android applications. Additionally, we take advantage of Android\'s built-in services and components to ensure our applications are efficient and secure.\n\nOverall, our focus is on creating a scalable and maintainable platform that can adapt to future needs while delivering a seamless user experience.','6','John\'s response touches on important aspects of Android development, such as thread management and adherence to SOLID principles for maintainability and flexibility.

How did you ensure compatibility and stability during this process?','Yeah, so in our application like when we access some of the hardwares in our mobile applications such as camera, we can take an example of camera. So we have a use case like the user can scan a vehicle identification number from the windshield in the vehicle. So for that, we need to access the mobile app camera hardware. So for this, first thing we\'ll consider is like we have to declare the camera permission in app manifest file. And then we need to have a runtime permission since in latest Android, the permissions won\'t be default given. So while invoking the camera, we need to present a runtime permission for the user. So we will be the permission dialog will be having accept and deny buttons. So only we\'ll get a callback, whatever the user selects either an accept or deny. So based on that, we can proceed to open the camera or if they are denying, we can show an error banner or an error dialog like we need the permission to proceed. So basically like we\'ll be having the runtime permissions and we have to declare the permissions in manifest. Similarly, if we need to access our Bluetooth from the mobile hardware. So similarly, we need to add those permissions in manifest file and we can register a broadcast receiver so that whenever there is a change in Bluetooth status, it will be notified to the mobile app.\n','One instance where I customized Android for a specific hardware configuration involved using the camera to scan vehicle identification numbers (VIN) from windshields. Ensuring compatibility and stability required several steps.\n\nFirst, we declared the necessary camera permissions in the Android manifest file, which is essential for accessing hardware components. Given the emphasis on security in the latest Android versions, we also implemented runtime permissions. This means that when the app attempts to access the camera, a dialog box appears asking the user to grant or deny permission. Depending on the user\'s response, we either proceed with opening the camera or display an error message indicating that permission is required.\n\nAdditionally, we ensured the app could handle various hardware configurations and screen sizes by testing it on multiple devices. This approach helped us identify and resolve any compatibility issues early in the development process.\n\nFor other hardware components like Bluetooth, we followed a similar strategy. Permissions were declared in the manifest, and we used broadcast receivers to monitor changes in Bluetooth status. This allowed the app to respond dynamically to hardware state changes, ensuring a smooth and stable user experience.\n\nBy following these steps, we ensured that our app was compatible with different hardware configurations and stable across various Android devices.','6','John\'s response provides a relevant example of customizing Android for specific hardware by discussing camera access for scanning VINs. He correctly mentions the need for declaring permissions in the manifest and handling runtime permissions, which are essential steps.

I\'m particularly interested in any system-level UI elements you\'ve worked on.','Yes, so for the UI related development, so in the initial days we were using XML to create an UI for our mobile application. So now recently Android has introduced the latest Jetpack Compose framework on the library, so which will be declarative kind of a framework, so which will be very useful and it will be faster compared to the XML based approach. So we\'ll be using all like a list views or grid views and we have various views such as text views and input text field where we can get the user input and the action buttons there like we have buttons and image view to show an image. So in case if it is a form kind of thing, so we have to use the input text field as well as buttons and drop downs. And so if it is, let\'s take an example of login page. So if user has to provide a username and password, then we need to provide, we\'ll be providing with two input text fields and the password text field has to be in input type of password so that the letters won\'t be visible whenever they type, instead of that we\'ll be showing with an asterisk and we can, we\'ll be, we have to provide a button so that they can click login to proceed.\n','In my experience designing user interfaces on the Android platform, I have worked extensively with both XML and Jetpack Compose. Initially, we used XML to create the UI, defining various views such as TextViews, EditTexts, Buttons, and ImageViews. While this approach was effective, it could become cumbersome for complex layouts.\n\nRecently, I transitioned to using Jetpack Compose, a modern, declarative UI toolkit introduced by Android. Jetpack Compose allows us to build UIs more efficiently and with less boilerplate code compared to XML. It is particularly useful for creating dynamic and responsive layouts. For example, when designing a login page, we can easily define two input fields for the username and password, ensuring that the password field masks the input with asterisks for security. We also include buttons for user actions like logging in.\n\nRegarding system-level UI elements, I have integrated notifications and alerts that interact with the system\'s notification manager. This includes designing custom notification layouts and handling user interactions directly from the notification shade. Additionally, I have implemented various system dialogs and toasts to provide feedback and alerts to users in a consistent and user-friendly manner.\n\nOverall, my approach to UI design focuses on creating intuitive and responsive interfaces that enhance the user experience while ensuring compatibility across different devices and screen sizes.','6','John\'s response outlines his experience with UI development using XML and Jetpack Compose, which is relevant to the question.

Can you please discuss a specific instance where you optimized an Android system for better performance?','Yes, so regarding the performance improvements, so we need to be very careful about it, otherwise if you are not concerning about it, it may end up with various errors or crashes or ANR issues like the app won\'t be responding. So the things which we need to keep in mind when we are developing the code, it\'s mainly like so in which thread it has to work. So if it is a background operations, so it should be working in IO thread, it should not work in a main thread so that it won\'t be blocking the main thread which ends up in ANR issue. So we make sure like all the IO related operations like making an API call and getting the response everything happens or reading the data from the database, everything happens in IO thread. So once we get the response to update the UI, we\'ll be using in the main thread, we\'ll be working on the main thread. Similarly, like so we need to make sure like whether any of the services is not tightly coupled to an activity so that so if it is coupled to an activity and object is not object reference to refer to an activity, it is not getting cleared. So during garbage collection, so it may end up in the memory leak. So it will end up in a crashes. So we need to make sure the objects are getting deallocated. So once it done with their use case, so that whenever the garbage collection happens, so it will be clearing all the unwanted objects so that the application will be in a correct state to work on. And so in case of any performance issue, we can use profiling from Android Studio, which is a tool which will help help us to see which is making an issue in our application like whether any object is taking more space or whether the object is getting referred has an reference for a longer time, and it\'s not getting cleared out. So we can find all those things from the profiling tool in Android Studio.\n','Performance optimization is a crucial element of mobile application development. In one instance, I enhanced the performance of an Android system by addressing Application Not Responding (ANR) issues and memory leaks.\n\nOur application frequently encountered ANR errors due to long-running operations being executed on the main thread. To resolve this, I shifted all I/O operations, such as API calls and database reads/writes, to background threads using Kotlin Coroutines. This adjustment prevented the main thread from being blocked and significantly improved the app\'s responsiveness.\n\nAdditionally, I addressed memory leaks by ensuring that services and background tasks were not tightly coupled to activities. This involved using weak references and carefully managing the lifecycle of objects to ensure they were properly deallocated when no longer needed. I also utilized Android Studio\'s profiling tools to monitor memory usage and identify objects that were not being garbage collected. This process allowed us to pinpoint and resolve issues where objects were holding onto references longer than necessary.\n\nBy implementing these optimizations, we greatly enhanced the app\'s performance and stability, resulting in a smoother user experience and fewer crashes.','6','John\'s response addresses the importance of performance optimization and mentions relevant concepts like thread management and memory leaks. He also correctly identifies tools like Android Studio\'s profiler for diagnosing performance issues. However, his response could be more impactful by providing a specific example of a performance issue he resolved, as well as the outcome of his optimization efforts. Additionally, mentioning any metrics or user feedback that demonstrated the improvement in performance would align his response more closely with the benchmark response.'),(342,63,45,412,99,'Collaboration is key in any project. Can you please tell me about a time when you had to collaborate with cross-functional teams to ensure a cohesive user experience?','yes as a mobile developer so we want to make sure so we collaborate with the cross-functional teams such as like the back-end teams mainly the back-end API teams since we are invoking their APIs so it has to be in a correct way so so we want to be in a same lane so that it won\'t make any issues whenever we are making an API call with our back-end team so we\'ll collaborating with them to get all the required contracts before making a change and we\'ll be having multiple calls with them to get it aligned what does our requirement and what is the expected contract to be configured in mobile app and so all the related things will be conveyed clearly and so apart from that so internally within our team we will be having a brainstorming session like with before proceeding with any works like how we can proceed this is there a better way if there is a difference in opinion among ourselves so that we\'ll get a conclusion so how we can take about this task how we can get through it if there is any challenges we can discuss on the same\n','Collaboration with cross-functional teams has been a vital part of my role as a mobile developer. One memorable experience was when we worked on a significant update for a connected vehicle application at Ford Motor Company. We needed to ensure seamless integration between the mobile app and the backend services, which required close cooperation with the backend API team. We held several meetings to align on the API contracts, ensuring that both teams had a clear understanding of the requirements and expected outcomes.

Please explain how you have implemented Android Security Best Practices in any of your previous projects.','so in the first project which I worked on is about a mobile banking application so since it\'s a banking related thing so we need to make sure all the in all the aspects of security since it deals with the transaction of amount with the customer information everything so for to make sure every security things are correctly implemented so we have few things like so hashing algorithms so we use hashing algorithm to hash all the passwords the user passwords so we use SHA-256 and SHA-512 hashing we have different things so we\'ll be using SHA-512 hashing to hash the password and send it to back-end so that even in between if someone is able to retry that password they can\'t able to find what password it is since we can\'t reverse back the hashing thing and all the API calls are encrypted and user data everything is encrypted and transmitted over the API request so that even if someone is interrupting because they can\'t able to retry back what data is since it\'s encrypted only the only using the only back-end keys will be able to decrypt the data using the key whichever the mobile app users so and we\'ll be we we used SSL pinning concept in our mobile application so we we have configured in the second network security XML file in Android application where we can pin the certificate and we can mention the certificate hash in our in that XML so that if if like if mobile app is trying to make any calls apart from that hash value then it will be restricted so only the domains with the which has the valid SHA value in that network XML security XML file the mobile app can able to make a API call so apart from that if someone is trying to change the domain while making the API call then the mobile app interrupts it and we have clear text traffic in Android manifest which will be which will be making this false so what it does is like it won\'t allow any HTTP connections so only the HTTPS connections it will be allowing in the while making an API call\n','Security has always been a top priority in my projects, especially in sensitive applications like mobile banking. In one of the banking applications I worked on, we implemented several Android security best practices to ensure data protection and integrity.\n\nFirstly, we utilized strong hashing algorithms such as SHA-512 to hash user passwords before sending them to the backend. This approach guarantees that even if the data is intercepted, the original passwords cannot be retrieved due to the irreversible nature of hashing.\n\nWe also encrypted all API calls and user data transmitted over the network using HTTPS, ensuring that data in transit remained secure. Additionally, we implemented SSL pinning by configuring the network security configuration XML file. This involved pinning the server\'s SSL certificate, which ensured that the app only communicated with servers that had the valid certificate hash specified in the configuration. This measure effectively prevented man-in-the-middle attacks by restricting API calls to trusted domains only.\n\nFurthermore, we disabled clear text traffic in the Android manifest by setting the `cleartextTrafficPermitted` attribute to false. This ensured that the app only allowed secure HTTPS connections, further enhancing data security.\n\nBy following these practices, we successfully created a secure environment for our users, protecting their sensitive information and ensuring the integrity of their transactions.','8','John\'s response effectively details his experience with implementing security measures in a mobile banking application, which is highly relevant to the question.

Instead, we developed a dynamic approach to retrieve the certificate data from our backend server.\n\nHere’s how we tackled the issue:\n\n1. **Initial Setup**: We started by hard-coding the certificate in the app, which worked well until the server-side certificate was updated.\n\n2. **Problem Identification**: We found that the app would stop functioning whenever the server\'s certificate was updated, as it continued to rely on the outdated certificate.\n\n3. **Dynamic Fetching Mechanism**: To address this, we implemented a system where the app would dynamically fetch the latest certificate from the backend server. We introduced versioning for the certificate data, so whenever the server updated the certificate, it also updated the version number.\n\n4. **API Call for Certificate**: The app was modified to make an API call to the backend server to verify the certificate version. If the version had changed, the app would retrieve the new certificate and replace the old one.\n\n5. **Implementation**: We removed the hard-coded certificate and established logic to download and store the new certificate dynamically. This ensured that the app always had the latest certificate without requiring users to perform manual updates.\n\nThis solution provided a seamless and uninterrupted experience for users, eliminating the need for frequent app updates and ensuring that the app consistently utilized the correct certificate for secure API calls.','8','John\'s response describes a real-world problem related to SSL pinning and provides a detailed account of the challenge and the solution implemented.

Next, I would check crash analytics tools like Google Play Console to view crash reports and stack traces, which would help identify the exact line of code or module causing the issue. Filtering by app version and device model can provide more targeted insights.\n\nUsing integrated analytics tools like Amplitude, I would analyze user flows to understand the sequence of actions leading up to the issue, which helps in replicating the problem in a controlled environment. For issues related to API calls, I would use monitoring tools like Dynatrace to track errors and performance metrics. By examining logs based on user IDs, I can pinpoint where the API calls are failing and why.\n\nWith the gathered data, I would attempt to replicate the issue in a development or staging environment, which is crucial for understanding the root cause and testing potential fixes. Once the root cause is identified, I would implement the necessary fixes and thoroughly test them in various scenarios to ensure the issue is resolved without introducing new problems.\n\nAfter deploying the fix to production, I would closely monitor the app\'s performance and user feedback to ensure the issue is fully resolved and no new issues have arisen.

How have you leveraged these languages to enhance application functionality?','yeah so kotlin is the recent language which we are using for Android app development so if you take kotlin we have so much of advantages of using kotlin some of the main thing is like it\'s null safe thing so the main problem in which we face in Android application day-to-day is like so many null pointer exception so if we if we do not handle the null properly in our app so it will make an error pointer exception which may end up in crashing the application since kotlin have so many things like null safe so we can declare a value as null so that if in case the value is getting a null value so we will be having all the handlings like will be having the null operator and we can use Elvis operator so that if there is an case like the mobile app is receiving a null value we have an next way or next plan what has to be happen if there is a null value so this advantages was there in kotlin similarly we have data classes in kotlin which we can able to store a data in the user session which will be helpful while making a pay call or while returning the data from the databases we will be having this data class models in an in kotlin we have some like we have around five scopes which will be very helpful during our development cycle like let run with allow and apply operators where we can able to assign this values easily which makes our code clean and easily flexible and so by so kotlin will support oops concept so we have all other oops based things like inheritance polymorphisms everything will be supported by kotlin which helpful to make the code clean and modularize so that if there is any change in change we don\'t want to change so many which won\'t affect much files and since since we are we are developing in a modularized way it will be helpful in it during our testing phase also\n','I have extensive experience with both Java and Kotlin in Android development, using these languages to enhance application functionality in various ways.\n\nIn the early stages of my career, I primarily used Java for Android development. Java\'s robust object-oriented programming features enabled me to create modular and maintainable codebases. I employed inheritance, polymorphism, and encapsulation to build scalable applications. For instance, I implemented complex business logic and managed asynchronous operations with AsyncTask and later with RxJava for more reactive programming.\n\nIn recent years, I have transitioned to using Kotlin due to its modern features and increased productivity. One significant advantage of Kotlin is its null safety, which helps prevent null pointer exceptions—a common source of crashes in Android apps. By utilizing nullable types and the Elvis operator, I can handle null values more gracefully and ensure the app remains stable.\n\nKotlin\'s data classes have been incredibly useful for managing data models, as they automatically generate boilerplate code like getters, setters, and `toString()` methods, resulting in cleaner and more concise code.\n\nKotlin also offers powerful scope functions such as `let`, `run`, `with`, `apply`, and `also`, which contribute to writing more readable and maintainable code. These functions allow for more concise manipulation of objects and reduce the verbosity often associated with Java.\n\nAdditionally, Kotlin fully supports object-oriented programming concepts, enabling me to continue using inheritance, polymorphism, and encapsulation to create modular and reusable code. This is particularly beneficial when working on large projects where code maintainability and scalability are crucial.\n\nKotlin\'s interoperability with Java has also been a significant advantage, allowing for a gradual migration of existing Java codebases to Kotlin without any disruptions.\n\nBy leveraging the features of both Java and Kotlin, I have enhanced application functionality, improved code quality, and ensured a more stable and maintainable codebase.','8','John\'s response highlights the advantages of using Kotlin for Android development, particularly its null safety features, data classes, and scope functions.

So when we implemented CICD pipelines it get reduced so much of manual works what we have done earlier. So we have the scripts for the CICD pipelines which will generate the build automatically we have Gradle W commands which will be running our code and will be generating the app and so we will be providing the path in the CICD so whatever path we give the generated APK will be stored in that path which will be from there we can download that APK and start testing it. Similarly, we had a pipeline to upload the generated APK directly to the Play Store console so that there won\'t be any manual works doing all these things.\n','At Tata Consultancy Services, the introduction of CI/CD pipelines significantly streamlined our development process and reduced manual efforts. \n\nBefore implementing CI/CD, we faced challenges such as manually generating APKs, sending them to clients for testing, and uploading them to the Google Play Console for approval and publishing. This process was time-consuming and prone to human error. \n\nTo address these issues, we implemented CI/CD pipelines using tools like Jenkins and GitLab CI. Here’s how it enhanced our workflow:\n\n1. **Automated Builds**: We created scripts within the CI/CD pipeline to automate the build process. By utilizing Gradle commands, the pipeline automatically compiled the code and generated the APK, ensuring consistency in every build and minimizing the risk of human error.\n\n2. **Continuous Testing**: The pipeline included automated tests that ran with each build, allowing us to identify bugs and issues early in the development cycle, which ensured higher code quality and stability.\n\n3. **Artifact Storage**: We configured the pipeline to store generated APKs in a designated location, making it easy for the QA team to download the latest builds for testing without waiting for manual intervention.\n\n4. **Automated Deployment**: One of the most significant improvements was automating the deployment process. The pipeline was designed to upload the generated APK directly to the Google Play Console, eliminating the need for manual uploads and accelerating the release process.\n\n5. **Notifications and Monitoring**: We also integrated notifications into the pipeline, ensuring the team was promptly informed of build statuses, test results, and deployment outcomes. This enabled us to quickly address any issues that arose during the CI/CD process.\n\nBy implementing CI/CD pipelines, we achieved a more efficient, reliable, and faster development cycle, allowing us to focus more on coding and less on manual tasks.

I use emulators to test applications across various Android versions and screen sizes, ensuring compatibility and a consistent user experience. For instance, when developing a new feature, I create multiple emulators with different resolutions and API levels to confirm that the UI and functionality remain consistent across devices. The Layout Inspector is invaluable for inspecting and debugging UI layouts. Recently, while working with Jetpack Compose, I monitored compositions with the Layout Inspector to identify unnecessary recompositions that could lead to UI lag, which helped me optimize performance. When managing local databases with Room, the Database Inspector allows me to view the database schema and data in real-time, making it particularly useful for debugging data-related issues. The Network Inspector tracks network requests and responses; for example, I used it to debug an API integration by examining request headers and response bodies to ensure they matched the expected format. The Profiler is crucial for monitoring app performance, helping me identify memory leaks and performance bottlenecks. I once detected an object that wasn\'t being garbage collected, which led to a memory leak, and fixing this issue significantly improved the app\'s stability.\n\nGradle is used for managing project dependencies and building the application. I configure dependencies in the `build.gradle` files to ensure all necessary libraries are included. For example, when adding a new third-party library for image loading, I updated the Gradle file and used Gradle commands to sync the project and build the app.\n\nADB (Android Debug Bridge) commands are vital for interacting with physical devices. I use ADB to install and run applications on physical devices for testing. When testing an app on a physical device, I connect it to the same network as my development machine and use `adb connect <IP>` to establish a connection, allowing me to deploy and debug the app directly on the device. Additionally, the `adb devices` command helps list all connected devices, ensuring that the device is properly connected and recognized by Android Studio.\n\nBy leveraging these tools, I can efficiently develop, test, and debug Android applications, ensuring they are high-quality and perform well.','8','John\'s response provides a detailed account of how he uses Android Studio, ADB, and Gradle in his development workflow, including specific examples of the tools\' functionalities.

This involved analyzing user behavior and preloading data that users were likely to need based on their past interactions with the app.\n\nWe utilized analytics tools to track and analyze user behavior patterns, which helped us identify the most frequently accessed features and the typical sequences of actions users took within the app. Based on this analysis, we implemented a caching mechanism that preloaded data for the most commonly accessed features, storing it locally on the device to reduce the need for frequent server requests. The caching mechanism was designed to update dynamically, ensuring that the preloaded data remained relevant and up-to-date without overwhelming the device\'s storage.\n\nThe predictive caching mechanism significantly improved the app\'s performance, resulting in faster loading times and a smoother overall experience for users. This innovative approach not only addressed the immediate performance issue but also provided a scalable solution that could adapt to changing user behaviors.\n\nBy thinking creatively and leveraging user behavior data, we successfully implemented a solution that enhanced the app\'s performance and user satisfaction. This experience reinforced the importance of considering unconventional approaches when traditional methods fall short.','4','John\'s response indicates an understanding of the importance of adhering to company rules and coding standards when solving problems.

So from starting only I have worked on Android automotive infotainment systems. In telematics, convent or radio features, I have used to develop HMI screens which works upon platform or we can say HAL provided by LG and framework provided by Google. It is AOSP. So yeah, we have used that AOSP and HAL provided by LG to develop HMI for these features in Nissan cars. Particularly automotive, we have used automotive components like for radio, let\'s speak about for radio. So for radio, we have used automotive components like tuner, hardware tuner which receives signals from signal generator and then we are able to proceed, we are listing these frequencies and tuning to particular frequency.

In my role, I have worked extensively on developing and customizing HMI screens for features such as telematics, connectivity management, and radio. These developments were built on the Android Open Source Project (AOSP) framework and the Hardware Abstraction Layer (HAL) provided by LG.\n\nFor example, in the radio feature, we utilized automotive components like hardware tuners to receive and process signals from signal generators, enabling us to list and tune into specific frequencies. For connectivity management, we integrated components such as Bluetooth, Wi-Fi, and vehicle hotspots to facilitate seamless connectivity features.

We utilized the Contract SDK provided by Xperi, which enabled us to fetch album art and logos for FM, AM, and DAB frequencies.\n\nThe challenge was twofold: managing native signals and internet radio. For native signals, we received data from the HAL provided by LG. To display album art and logos, we needed to send this data to the Contract SDK, which would return the necessary metadata. We then combined this metadata with the native signals to create a complete user interface for the end user.\n\nFor internet radio, which operates entirely over the internet, we also relied on the Contract SDK to fetch and display metadata. Integrating these components required careful coordination to ensure a seamless data flow and user experience.\n\nOvercoming these challenges involved extensive testing and debugging to ensure that the data from the HAL and the Contract SDK were correctly synchronized and displayed. Effective communication with the Xperi team was crucial for promptly resolving any issues. This experience significantly enhanced my skills in integrating third-party libraries and ensuring smooth functionality within the Android platform.','6','Ajay\'s response provides a clear example of integrating third-party libraries, specifically mentioning the Contract SDK from Xperi.

My main objective is to create a user-friendly and intuitive interface. It is essential that the UI remains simple and accessible for drivers, minimizing distractions. Safety is of utmost importance, so certain features are restricted while driving and are only enabled when the vehicle is parked or accessible to passengers, but not the driver.\n\nI start my process with a comprehensive review of the specifications. In the Nissan project, we had two types of specifications: HMI and functional. The HMI specification outlines the layout, components, and visual elements, while the functional specification details the behavior, flow, and interactions of these components.\n\nAfter gaining a clear understanding of the specifications, I visualize the screens from the end-user\'s perspective to ensure the design aligns with their needs. I then identify the technical requirements, such as the necessary Android APIs. If the required APIs are available in the AOSP code, I utilize them according to the guidelines. If not, I collaborate with the LG team to integrate the necessary APIs into the platform.\n\nOnce all requirements and uncertainties are addressed, I proceed with the implementation, following Android guidelines and standards. This structured approach ensures that the user interface components are both functional and user-centric, providing a seamless and safe experience for end-users.','6','Ajay\'s response outlines his approach to designing and implementing user interface components, emphasizing user-friendliness and safety. However, the response is somewhat disorganized and could benefit from a more structured explanation.

One example of how I enhanced system performance was during the development of the Conman feature for Nissan vehicles.\n\nWe faced a challenge where, after a cold start, the system would occasionally show a black screen and take time to reconnect to Android Auto or CarPlay, leading to delays in resuming playback. This intermittent issue occurred in about three out of fifteen instances, which was unacceptable for user experience.\n\nTo tackle this, we implemented several strategies:\n\n1. **Thread Management:** We moved all long-running tasks off the main thread to prevent UI blocking. UI updates remained on the main thread, while API calls and database operations were shifted to background threads.\n\n2. **Prioritization:** We prioritized tasks that were critical immediately after startup. For example, if Android Auto was previously connected, we focused on fetching and loading data related to Android Auto first, deferring less critical tasks to ensure quicker reconnection and playback.\n\n3. **Code Optimization:** We reviewed and eliminated any unused code and streamlined the logic to ensure that only necessary operations were performed during startup.\n\nThese optimizations significantly improved the performance of the Conman feature, resulting in a smoother and faster user experience. By prioritizing critical tasks and managing threads effectively, we were able to reduce the occurrence of black screens and enhance the reconnection time to Android Auto and CarPlay.','6','Ajay\'s response indicates a clear understanding of the importance of performance optimization and provides a specific example related to the Conman feature.

Security and compliance are vital aspects of automotive infotainment systems. In my previous projects, prioritizing Android security best practices was essential.\n\nWe adhered to the security standards established by Google for Android Automotive development, which are designed to protect the system. For instance, certain features, such as video playback, are restricted while the vehicle is in motion to prevent driver distraction. These restrictions are clearly outlined in our project specifications and must be strictly followed.\n\nAdditionally, we pursued various certifications to ensure compliance. For example, in the Conman feature, we successfully completed the Android and CarPlay certifications. These certifications, overseen by Google, require our code to meet specific security and compliance criteria before it can be approved for release.\n\nWe also conducted regular automated testing, including the Compatibility Test Suite (CTS) and the Automated Test Suite (ATS), to ensure ongoing compliance. These tests are performed periodically to identify any security or compliance issues.

So we are like if there are some file reading or something related to IO, we need to perform the task, then we are using coroutine for coroutine with context of a dispatcher IO. So this way there are many things that required Kotlin or Java implementation to pop up the issue. One major issue we found and we have resolved that I recall is we have a requirement in telematics feature, we have a requirement that we need to change the application name at a runtime, not just application name, but its package name also like in settings in applications, we can see all the application which are currently installed. So and there also the application name should be updated while runtime. So after many trials and many research, we like team was not able to find the root cause and how to implement this kind of requirement. Finally, we have figured out that we can do one thing like we can use RROs. So to overlay the string at a runtime. Now in that also we have implemented two RROs, one is for vehicle brand like for Nissan there is one RRO and for Renault there is another RRO. So at runtime it will like enable and disable, it will change the application name like telematics application name. So after many research and POC, we found that this can be the way. So final way we find out that one string ID and two different string names in different RROs will resolve the issue. So that kind of issues we faced and we have resolved.\n','One complex coding problem I solved using Kotlin involved optimizing the performance of the Conman application. We needed to move long-running tasks, such as file I/O operations, off the main thread to improve responsiveness. To achieve this, we utilized Kotlin coroutines with the `Dispatchers.IO` context to handle these tasks asynchronously, ensuring that the main thread remained available for UI updates.\n\nAnother challenging issue arose with the telematics feature, where we needed to change the application name and package name at runtime. This change had to be reflected in the system settings, displaying the updated name for the installed application.\n\nAfter extensive research and trials, we discovered that Runtime Resource Overlays (RROs) could be used to overlay strings at runtime. We implemented two RROs: one for the Nissan brand and another for Renault. By enabling and disabling these RROs at runtime, we could dynamically change the application name.\n\nThe solution involved defining a single string ID with different string values in the two RROs. When the brand changed, the corresponding RRO was activated, updating the application name accordingly. This approach required significant experimentation and proof of concept work, but ultimately, it resolved the issue effectively.\n\nThis experience enhanced my problem-solving skills and deepened my understanding of Kotlin\'s capabilities, particularly in handling asynchronous tasks and dynamic resource management.','8','Ajay\'s response provides a good example of a complex coding problem he solved using Kotlin, particularly mentioning the use of coroutines for performance optimization. However, the explanation could be clearer and more structured. Ajay could improve by outlining the problem, the steps taken to solve it, and the outcome more succinctly.

We needed to manage user authorization for emergency calls, such as e-calls for driver assistance.\n\nThe process involved several steps and interactions with various cloud services. When a user initiated an e-call, the request first required authorization by the platform to ensure the correct user was identified. This user authorization was handled by a service called iKeyLink Manager, which verified the user\'s credentials.\n\nOnce authorized, the request was sent to the Camrion server, hosted on AWS. The Camrion server then initiated the e-call to Nissan\'s assistance services. Similarly, for other types of calls, like breakdown or maintenance calls, the process involved communication between the Nissan assistance services, the Camrion server, and the WinX server, which relayed the information back to the vehicle.\n\nDuring this project, we encountered challenges related to the seamless integration of these services. To address these issues, we collaborated with multiple teams responsible for different parts of the system. We employed containerization to create isolated environments for testing and debugging, ensuring that each component functioned correctly before being integrated into the larger system.\n\nBy leveraging cloud platforms and containerization, we streamlined the user authorization process and ensured reliable communication between the vehicle and the cloud services. This approach not only improved the performance and reliability of the telematics HMI but also enhanced the overall user experience by providing timely and accurate assistance during emergencies.','4','Ajay\'s response indicates some familiarity with cloud platforms and containerization, and he attempts to describe a relevant scenario involving user authorization in telematics HMI.

Let me share an example of how I used these tools to resolve a complex issue.\n\nIn one instance, we encountered a problem where an Android Automotive Infotainment system was intermittently crashing during certain user interactions. To address this, I extensively utilized Android Studio.\n\n1. **Android Studio:** I started by implementing and debugging the code within Android Studio. The built-in debugger allowed me to set breakpoints and step through the code to identify the source of the issue. Additionally, I used the Logcat feature to filter and analyze logs, which provided valuable insights into the root cause of the crashes.\n\n2. **ADB (Android Debug Bridge):** To further investigate, I employed ADB commands. For example, I used `adb shell` to access the device\'s file system and examine different partitions. This enabled me to check configuration files and logs directly on the device. I also used `adb logcat` to capture real-time logs, which were crucial for understanding the sequence of events leading up to the crash.\n\n3. **Gradle:** Gradle played a vital role in managing the build process. I used Gradle tasks like `assembleDebug` to build the application in debug mode, making troubleshooting easier. Moreover, I managed dependencies through Gradle, ensuring that all necessary libraries were included and up-to-date. This was particularly important when we needed to add or update SDK dependencies to resolve compatibility issues.\n\nBy combining these tools, I was able to identify the problem, which stemmed from a specific third-party library causing conflicts. After updating the library and adjusting the code accordingly, the crashes were resolved.\n\nThis experience underscored the importance of effectively utilizing the right tools to troubleshoot and resolve complex issues in Android development.','4','Ajay\'s response mentions the use of Android Studio, ADB, and Gradle, but it lacks a clear example of troubleshooting a complex issue. The response is somewhat general and does not provide a structured approach to how these tools were used to identify and solve a specific problem. Ajay could improve by providing a detailed example that includes the steps taken to troubleshoot the issue, the discovery process, and how the tools were instrumental in resolving the problem, as illustrated in the benchmark response.'),(395,68,42,375,91,'Imagine you have a feature in an Android application that is causing significant battery drain. Without writing code, can you please explain your approach to identifying and resolving this issue?','Okay, so first of all I need to find out the cause why the application is using significant amount of memory and because of that the battery drainage system issue is occurred. So first of all I need to find the root cause using logs or by doing multiple test cases like what is the exit scenario where this kind of issue is occurred. So I will do multiple test cases, I will do multiple test, manual test, I will go through the logs then I will find the root cause. In order to resolve okay if still the root cause is not found then I will go through my code where I used the resources like if I use let\'s say in my application camera is used so obviously camera is using more battery than other components. There are other components also which uses battery but camera is like using more that I know. So in that context I will check if my application is closing or releasing the resource at a time after particular time or not. Like if the resource is idle and still my application is using then in order to improve the performance and reduce the battery usage I need to release the resources after particular usage like if my application has the feature to like click the photo. So after clicking photo the camera resource should be released. So I will check this kind of resources used in my code and it is released after particular time or not. So threading is also major like significant component like if my application runs on multiple threads at a time and it uses many CPU like multiple CPU cores at a time then I need to like reduce the multithreading and try some other way to optimize that kind of scenarios. So yeah I will firstly check for testing then log analysis then if still not found then I will go through my code to check that if my application is using any resource or not and if resources are like staying idle and not releasing from my application from my application process then I need to release them. In these ways I can like reduce the battery drain issue.\n','Addressing significant battery drain in an Android application requires a systematic approach to identify and resolve the issue. Here’s how I would tackle it:\n\nFirst, I would analyze the logs to identify any patterns or specific scenarios where the battery drain occurs. This involves running multiple test cases and conducting manual tests to consistently reproduce the issue.\n\nIf the logs do not reveal the root cause, I would review the application\'s resource usage. Components like the camera, GPS, or network can significantly impact battery life, so I would check if these resources are being properly managed. For example, if the camera is used, I would ensure it is released immediately after the photo is taken.\n\nNext, I would examine whether there are any background services or tasks running unnecessarily. Optimizing background processes to run only when needed can help reduce battery consumption.\n\nIf the application uses multiple threads, I would assess their management. Excessive or poorly managed multithreading can lead to high CPU usage, which drains the battery. I would look for opportunities to reduce the number of active threads or optimize their execution.\n\nAdditionally, I would check if the application is using wake locks correctly. Wake locks should be used sparingly and released as soon as they are no longer needed to prevent the device from staying awake unnecessarily.\n\nFinally, tools like Android Studio\'s Battery Profiler can provide insights into battery usage patterns and help pinpoint the components consuming the most power.\n\nBy following these steps, I can systematically identify and address the factors contributing to battery drain, ensuring the application is optimized for better battery performance.','6','Ajay\'s response outlines a general approach to identifying and resolving battery drain issues, including testing, log analysis, and resource management. However, the response could be more structured and include specific steps and tools used in the process. Ajay could improve by detailing a systematic approach, such as using Android\'s Battery Profiler to analyze power consumption, reviewing wake locks, and optimizing background processes, as described in the benchmark response.

So I also faced many scenarios. In that case, what I am doing, what I do always is like we judge the solution like in software industry for one problem there can be multiple solutions. So in that context, what we can do is which solution is better and how we can judge is there are particular scenarios like if it is a DSA problem like data structure problem then we judge based on the time complexity and space complexity. So similarly in our project or in normal real life projects, if there are multiple approach then we need to check its feasibility, its maintainability, how it is resolving the issue like performance of that solution. So based on these factors, we do discussions with that team member like I do discussion with that team member. My solution is taking this much time and this is the code, this is the solution. Similarly he also comes with the approach, he also comes with the solution and based on this, we have just reviewed our solutions and codes. If his approach is better than me then it will be absolutely like okay for me to go with his solution. Similarly if my approach is good in some areas then in that case he should also accept that we should go with this solution or else what we can do is we can do a third review like from our team leader or from client only. So in that context we can provide two POCs like proof of concept of both solutions and based on these factors like optimization or performance or how it is implemented, is it a complex code or easy code, is it a complex to maintain or to scale. So on these factors the person can judge that which solution we should go for.\n','Working with team members who have different approaches to a project is quite common. Here\'s how I handle such situations:\n\nIn one instance, I was involved in a project where my method for solving a problem differed significantly from a colleague\'s. Rather than viewing this as a conflict, I saw it as an opportunity to explore multiple solutions.\n\nFirst, we initiated an open discussion where each of us presented our proposed solutions. I explained my approach, outlining the logic, expected outcomes, and potential trade-offs, while my colleague did the same for their method.\n\nNext, we established criteria to evaluate both solutions, considering factors such as feasibility, maintainability, performance, and complexity. For instance, in a data structure problem, we assessed time and space complexity. For our project, we examined how each solution affected performance, as well as its ease of maintenance and scalability.\n\nWe then collaboratively reviewed each solution against these criteria. If my colleague\'s approach demonstrated better performance or was easier to maintain, I was open to adopting their solution. Conversely, if my method had advantages in certain areas, I expected the same openness in return.\n\nIf we couldn\'t reach a consensus, we sought a third-party review from our team leader or even the client. We provided proof of concepts for both solutions and allowed them to assess based on the established criteria.\n\nUltimately, based on the review, we decided on the best solution and proceeded with its implementation. This collaborative approach ensured that we selected the most effective solution while fostering a positive and productive team dynamic.\n\nBy focusing on objective criteria and maintaining open communication, we were able to resolve differences constructively and enhance the project\'s outcome.','6','Ajay\'s response demonstrates an understanding of teamwork and the importance of evaluating different approaches to a problem.

While working on the Ford Credit application, I focused on improving its overall performance.\n\nI prioritized the user interface by using SVG images for icons, as they are lightweight and scalable, which helps reduce load times. I implemented reusable components to minimize code redundancy and enhance efficiency, and I utilized RecyclerView for effective list rendering.\n\nTo optimize data handling, I employed efficient data structures and coroutines. This approach allowed me to perform background tasks without blocking the UI thread, ensuring smooth user interactions.\n\nI reduced the use of static elements to prevent memory leaks and facilitate proper garbage collection. Additionally, I applied the singleton design pattern to manage shared resources effectively.\n\nI carefully managed background services to ensure they stopped after completing their tasks, which helped conserve battery life. I preferred bound services for better control over their lifecycle.\n\nThese combined strategies significantly enhanced the app\'s performance.

I used secure preferences to store data in an encrypted format, decrypting it only when necessary. Protecting data is crucial, so I made sure that HTTPS is utilized for secure data transfer. For token-based authentication, I implemented JWT or OAuth 2.0, passing tokens with every API call to enhance security.\n\nI also integrated biometric authentication for user convenience and security, allowing users to log in effortlessly with a simple thumbprint. To strengthen code security, I employed ProGuard, which obfuscates the code and makes decompiling difficult. Additionally, I implemented SSL pinning to prevent man-in-the-middle attacks by pinning a certificate and ensuring secure handshaking with the server during network calls.\n\nI practiced effective resource management by releasing objects after use to prevent memory leaks and optimize performance. Testing and monitoring are vital, so we conducted regular security audits to identify and address vulnerabilities.\n\nThese measures have been consistently applied in my current and previous projects to ensure robust security compliance.

Okay, so when when I say that we are using the Elasticsearch clusters, okay, that needs an endpoint to be connected with okay And that in point is hosted as a secure way and we are connecting to it with the help of username and password Okay, so basically when When we have set up that Elasticsearch cluster, we have set up that into the Kubernetes So each node or each part of Elasticsearch is acting as a single node in the machine So all of this cluster needs to be connected to the service or that will be on the load balancer on the AWS side basically that needs to be Hosted somewhere in the route 53 so that you will be able to get access to it Okay, so what we do is like we created and we created a service that connects to all these nodes Okay, that reads data that puts data whatever the operations are there that service helps us In this service, we have to connect an ingress. Ingress will act as an internal load balancer for all of our for all of our nodes and all of our clusters. So in this cluster we will access the internal load balancer application in the AWS. Internal load balancer will be connected to the certificate HTTP means secure protocol certificate and also it will be connected to the Route 53 and DNS entries that we have to make. So that\'s how we are using HTTP or HTTPS protocol for our data communication with Elasticsearch. Also, we are using this HTTPS protocols to our API that is explicitly Made for the different clients that we are hosted on the Lambda Okay, so that Lambda is being connected to the API gateway. API gateway is act as a Act as an intermediary between Lambda and the client. So whatever the request comes to API gateway It will be given to the Lambda that will process the request and revert back to the client with the appropriate response So this in this way API gateway also act as an HTTP creates an HTTP protocols Protocols to connect to your client to your database So basically that\'s where we are using HTTP as HTTP protocols for our data use cases Okay, again, how do we make sure? The data integrity with it is because we are sure we keep the logs. Basically it checks every Parameter that needs to come here that needs to be common that needs to go from our system We have that kind of a mechanism that validates the data. Is it correct or not? So based on that we make sure the data integrity that we are giving out of this Protocol is correct and it has a secure HTTPS site is a certificate We are reliable on it\n','I would like to share some insights on using MQTT and HTTP protocols. For real-time data communication, we utilize HTTP and HTTPS protocols, which ensure secure communication.\n\nFor example, when connecting to Elasticsearch clusters, we use HTTPS. Each Elasticsearch node, hosted in Kubernetes, functions as an individual unit. These nodes connect to a service through a secure endpoint that requires a username and password. This service, managed by an internal load balancer, is hosted on AWS Route 53, ensuring secure and reliable communication.\n\nAdditionally, for our APIs hosted on AWS Lambda, we also employ HTTPS protocols. The API Gateway acts as an intermediary between the client and Lambda. It receives requests from the client and forwards them to Lambda, which processes and responds to these requests.\n\nTo maintain reliability and efficiency, we keep logs and validate every parameter to ensure data integrity. We use secure HTTPS certificates to guarantee the reliability and security of our communications. As a result, our data communication protocols are both dependable and efficient.','6','Bhushan\'s response provides a detailed explanation of how HTTP and HTTPS protocols are used in his projects, particularly with Elasticsearch and AWS services. He discusses the setup of secure connections and the use of API Gateway as an intermediary. However, the response could benefit from a clearer structure and focus on the efficiency and reliability aspects of the protocols. Additionally, Bhushan could improve by directly addressing MQTT and providing specific examples of how he ensured the reliability and efficiency of these protocols, as mentioned in the benchmark response.'),(418,69,35,413,100,'Could you please describe a project where you were responsible for real-time data processing and the challenges you faced during its implementation?','Okay, real-time data processing and the challenges that we face. So when it comes to the processing of the real-time data, we mostly face the challenge of processing time, the performance of our processors or the executors. So what we do basically for that, okay, let me give an example of what we have done, okay. So basically, we pull the data from the folders, put that data to Kinesis. So now from there, we have to make sure that data is being processed in a particular time or it should be processed in near real-time, basically. So we make sure that the concurrency of the Lambda is accurate, okay, and whatever the records is getting processed, it should be processed once, okay, and that\'s how we measurely say that the data is being processed at a near real-time to real-time. So let me give an example in terms of Lambdas that we are running, okay, once the data comes to the Kinesis, okay, from there, we can set the batch, okay, batch of 25, let\'s say, 25 articles to be processed in a single Lambda. So it will reduce the timing of like a spinning if your Lambdas and the connections that you make and the global variables that you make. So at that way, you can tackle a challenge of data-getting process in a slower process. Again, the challenge was like within this time range, we have to send it to Elasticsearch and send it to a different process like for the Kafka log consumption, okay. So what we have to do like we have to process this data, process this 25 articles to Elasticsearch and then we process like a 50 logs for this 25 articles, one log has started when we start processing the article at a time and one when we completed processing this article, we send two logs for each of the articles. So it will be around 50 logs for 25 articles and that time how we are doing like we are selecting all of those logs in a list and when pushing this log to the Kafka, we are pushing in a batches. So when we push it, we will push it in a batch but Kafka will take it as a single article, okay. So we will flush those 25 articles or 20, sorry, we will flush that 50 records or 50 logs in a batches, let\'s say the batch of 25 each. So at a time, 25 batches, 25 logs will be flushed and your Kafka queue, internal Kafka content, Kafka mentors and internal queue that will be pushed to the, that will get flushed at a time. So it will reduce the time of connection to the Kafka and it will also make sure the records have been pushed successfully. Apart from that, in Elasticsearch what we do is like we can update record one by one but we don\'t do that. What we do is like we bulk push those records in the Elasticsearch. It will reduce your time to connect to the Elasticsearch and it will also helps you reduce the repetitive way of pushing to the Elasticsearch. So basically batching thing that we have, basically the performance thing that was the major challenge and in a batching way and in a parallel way that we have optimized and that\'s how the challenge has been solved.\n','I would like to share my experience with a project focused on real-time data processing. At Onclusive, I managed real-time data and encountered several challenges throughout the process.\n\nOne major task involved processing data from Kinesis in near real-time. It was essential to ensure timely processing while maintaining high performance. We optimized the concurrency of AWS Lambda functions and implemented data batching to improve efficiency. For example, we processed 25 articles in a single Lambda function, which significantly reduced the overhead associated with launching multiple Lambdas.\n\nAnother challenge we faced was sending the processed data to Elasticsearch and Kafka. We generated logs for each article—one at the beginning and one at the end. By batching these logs and sending them to Kafka in groups of 25, we enhanced both efficiency and timeliness. This approach minimized connection times and ensured successful log submissions.\n\nFor Elasticsearch, we utilized bulk operations to push records. Instead of updating records one by one, we sent them in bulk, which decreased connection times and repetitive tasks.\n\nBy optimizing concurrency, batching data, and employing bulk operations, we effectively addressed the challenges of real-time data processing, leading to a more efficient and reliable system.','7','Bhushan\'s response provides a detailed account of his experience with real-time data processing, including specific examples of challenges and solutions related to Lambda concurrency, Elasticsearch, and Kafka batching.

Can you please walk me through a complex pipeline you\'ve developed and how you ensured its scalability and maintainability?','Okay, there are multiple pipelines that I have been worked on till now. So consider a complete pipeline of polling the data, transforming the data, enhancing the data and pushing that to the Elasticsearch. This is a complete one single pipeline that I have been working on. So what we do, a complete pipeline that I have been working through, there are a lot of pipelines, but this is one kind of example to look, what we do, each interval, this Python script is running on AWS ECS, that is Elastic Container Service that pulls the data at a certain interval of time, that push 500 articles to the Kinesis. Now we process that data, process that data based on the Lambda data. In that processing, we transform that data into totally different formats. That format has been completely supported by us, because we have hundreds of sources and hundreds of sources will not give us the data in a particular format that we want. So we do that at our own side, data transformation, data validation and all those stuff will be done with the base of Event-Based Triggered Lambda. Now that will firstly segregate the useful data, if any data is not useful, then we will scrap the data. And based on the field mapping and the validations, we will map the data, transform if required in a different kind of a field or in a different kind of a data type, we will transform that data. And then there are some enhancement needs to be done. So for that, what we do is we keep this data transformed to a different Kinesis, from there another Triggered-Based Lambda, Event-Based Lambda get triggered, there we do enhancement. We add publications, we add licenses, we add validations or the owner of the data, all those things we add and from there we will push that data to the Elasticsearch. So this is the pipeline that, this is one of the complex pipelines that we have worked. Again, in the enhancement of data, some of the fields are coming like an author, that is coming from the DynamoDB. We push, pull that data from the DynamoDB and append that into the articles. And this DynamoDB is not getting filled directly, we are filling that author\'s details from somewhere else, that is a different pipeline running in, but those Dynamo details or the DynamoDB author fields are appended internally in our own enhancement fields. And after that, we will push that data to Elasticsearch. Parallelly, that data goes for percolation, percolates from where you will get the articles. So percolate cluster works over there that creates, generates the query from your article. So there as well it works. Another pipeline that I am working on is like in a beam pipeline. So basically, when all the data, when the source push the data to a Kafka topic, on the Kafka topic of consumer or executors working, that executors are paralleling, multiple executors are working parallelly based on group IDs on all those stuff. Okay. So what we will do is like we paste the data in a pipeline, basically in a groups or in a batch. Okay. What we\'ll do, we do segregated data and we transform that data in a different, different way. Okay. So basically, all the things, the enhancement, all those things done in the pipeline only and this will be sent to a different Kafka topic. There will be a failure of our data. If any failure, we will send that data to DLQ. That is dead data. Okay. But we\'ll take example of the pass or the good example, like a good flow only. Okay. Once this data is getting processed, processed successfully, we push that data to a different topic. From there, our esync application works. That is a man, that is a flink, that is a beam again, Apache flink and Apache beam application again. Okay. That pulls the data, this data. It takes the data in which, what kind of a data it is and push that data to that kind of index. That kind of index is a elastic system. So all this thing, all this enhancement and all this transformation has been done into this pipeline. This is the complex pipeline that we are working together.\n','I will guide you through a complex data pipeline. I have worked on many pipelines, but this one is particularly intricate.\n\nConsider a pipeline designed for polling, transforming, enhancing, and pushing data to Elasticsearch. This pipeline, which operates on AWS ECS, pulls data at regular intervals, sending 500 articles to Kinesis. From Kinesis, Lambda functions process and transform this data, as it must be converted into different formats due to the varied sources.\n\nFirst, we segregate the useful data, validating and mapping fields while transforming data types as necessary. Next, we enhance the data. A second Lambda function, triggered by events, adds details such as publications, licenses, and ownership. We also retrieve additional information, like author details, from DynamoDB. Finally, we push the enhanced data to Elasticsearch.\n\nSimultaneously, this data undergoes percolation, generating queries from the articles. Another complex pipeline involves Apache Beam and Kafka. Source data is pushed to a Kafka topic and consumed by parallel executors. The data is processed in batches, transformed, and enhanced within the pipeline. Successfully processed data is sent to a different Kafka topic, while failures are directed to a Dead Letter Queue (DLQ).\n\nAn application using Apache Flink and Beam pulls this processed data and indexes it in Elasticsearch. By utilizing batching, parallel processing, and robust error handling, these pipelines ensure scalability and maintainability.\n\nThus, our data pipelines are both complex and efficient.','7','Bhushan\'s response is highly detailed, explaining the steps involved in a complex data pipeline from polling to pushing data to Elasticsearch. He discusses the use of AWS ECS, Lambda, Kinesis, DynamoDB, and touches on error handling with DLQ.

Okay. Why? Okay. Between, if you have to choose between Azure and Google Cloud Platform, okay, first thing, first preference will be goes to GCP. Why? Why? Because the services GCP provides, that is recommendable. Okay. That is a faster availability and also it\'s easy to use. Also, it\'s also a cost-beneficial. So, that\'s the major factor building any of your application on the GCP. Mostly, if you see, this GCP is being used and trusted by the banking side because of the data security protocols and all those things that is being easily taken care in the GCP. The security things, data security or the governance things, that will be easily useful. In, let\'s say, the Royal Enfield, there for sure there will be some, like customers\' data that needs to keep very secure. Their financial details, we need to keep, their card details, all those payment details, we need to keep it very secure. So, in my terms, GCP will be a much better option in terms of Azure and GCP. But again, if we are choosing a different option as well, if you\'re looking for a different option, AWS will be also a good competition for GCP. That we can discuss later. But as per your question, GCP will be a good choice and a better choice.\n','I need to choose between Microsoft Azure and Google Cloud Platform (GCP).

Additionally, GCP is cost-effective, which is a significant advantage.\n\nGCP is trusted by the banking sector due to its robust data security protocols. For Royal Enfield, where customer data security is essential, GCP would be a wise choice.

How would you approach diagnosing and resolving this issue without writing code, just verbally?','Okay, I got I got you want like something if we are occasionally missing any messages or losing any messages in the path cost stream. Okay, we I have identified this similar kind of an issue in my recent project. Okay, recent workflow. Okay, where we were losing an occasional message means it was it was it was a different fault. Okay, but what we can do to debug this issue is like first we need to check the offsets. Okay, we need to check how many data are there in the offset. Okay, or in the topic, how much offset has been raised. And all these things we can check again, the size of data, the replication factor, all this we can also check. Okay, we can keep it as a safety for the safety as a replication factor, we will be really helpful. If we are losing any data, first, we need to check the acknowledgements are there is this one kind of a data is missing or basically we will get a report that this data is missing. Can you please find out so based on that we will do all these record is being ever inserted into Kafka stream. So we will for sure get somewhere as an acknowledgement that the data has been processed to the Kafka topic that we can look in. Okay, if that has been lost, okay, basically Kafka may not lose any data. But if it has been lost, we need to debug internally how the Kafka streams are working at your end. And all those things we need to do basic without without checking the code or consuming what we can do is like we can if if any any consumer is working on that. So basically Kafka provides its own internal consumer to check if the data is present or not. So we can run that and we can get what kind of what data is present in the Kafka streams. And yeah, that will be much helpful to debug the issue that we are facing. Also, we can check a Kafka logs. Kafka keeps their failure logs and everything. If any day there is a failure of the message logs for anything we can for sure get over there with verbally. So the same is for everybody. So we can for sure get there anything that will be nice for us to debug deeper in purpose.\n','To diagnose and resolve message loss in Kafka streams, we should first check the offsets. It is essential to determine how many messages are in the topic and how much the offset has advanced. \n\nNext, we need to examine the replication factor, as ensuring sufficient replication is crucial for protecting against data loss. We must also verify acknowledgments to confirm that messages are being acknowledged and not lost during transit.\n\nAdditionally, we can review Kafka\'s internal consumer logs.

First might be the case of failure of the data or the data that incoming data is too huge. Okay, so we need to identify those things first. First thing will be like, let\'s take an example, if we are getting any failures, okay, let\'s say your data is getting filled and it\'s been pushed to the BLQ, for sure that is consuming, that will be taking a lot of time to for the failures to come back to your executor or you need to change, if that has been handled correctly or not, okay, again, the issue in the same way will be like, we might be enhancing some of the data with some API with some endpoints or we will be pushing the data to the certain endpoints, okay, on certain database clusters. So we need to check that, are those taking an optimal time or are those taking a required time or what, the time duration, we can check that, okay, from logs, we can definitely get that. Again, there will be case that we might be receiving a lot of data from our source side that the data has been pushed a lot in the last hour. So from, if we want that data is getting lagged and we want that to be processed, we can increase our executors, parallel executors from Kafka, whatever the executors we are working might be a PySpark or might be the Apache Beam or Apache Flink, that we can increase the executors at a time to process the data faster, okay, but that needs to be identified. So verbally, we can only guess that if any failure, any time duration, latency between our services that we need to identify and also the data that is coming in, is it in the right format, is it in the right size and the number of data that we are receiving at a certain level of time, we need to check all those things. So, yeah.\n','We need to address the delays in real-time data processing by considering several key factors. \n\nFirst, we should investigate any data failures. If numerous messages are failing and being sent to the Dead Letter Queue (DLQ), this can be quite time-consuming. It is essential to ensure that these failures are managed effectively. \n\nNext, we need to evaluate any external API calls or database interactions to confirm that they are functioning efficiently. By reviewing the logs, we can identify any latency issues. \n\nAdditionally, we should consider the volume of incoming data. If the volume is excessively high, it may overwhelm the system. Increasing the number of parallel executors, whether using PySpark, Apache Beam, or Apache Flink, can facilitate faster data processing. \n\nFinally, we must verify the format and size of the incoming data to ensure it is appropriate and manageable. \n\nBy identifying failures, reviewing external interactions, managing data volume, and increasing executors, we can effectively reduce the lag in real-time data processing.','6','Bhushan\'s response identifies potential causes of lag in real-time data processing, such as data failures, API or database latency, and the volume of incoming data.

Particularly with the storage problem that I solved, I have told in my introduction that I\'ve been working since from six months, five months to six months, with the Elasticsearch, setting up Elasticsearch with Kubernetes. So the thing was, we need a local SSD for the faster retrieval of data. Or any EBS volume block or the network storage block would not be here for the faster retrieval of data. So the major challenge was to create a storage class for this, because it was not given in the Kubernetes to get a local storage with whatever the present storage classes. GP3, GP2, all those are for the EBS blocks, and that cannot be used. So basically, what we have to do is we have to go for a third-party solution that will be an open EBS. What it gives, it provisions the local storage. For this, we need that storage to be mounted. So when it comes to a local SSD on a virtual machine, we need to mount it. But you cannot mount SSD for hundreds of machines by just logging to it and checking if the volume is mounted, because that\'s an auto-scaling cluster, right? It might be possible that some days that 80 machines are required. It might be possible that 100 machines are required. But that will definitely be out of scale. For that, you need to write a script. So I have wrote a script to overcome that challenge, that it will identify on the run. Whenever you spin up the machine, it will identify the storage over there, if SSD storage over there. And it will mount the SSD on that particular node, OK? So that\'s how we have tackled a storage problem with our Elasticsearch cluster. And that has been tackled easily. OK, coming to the different point of view over here, if the cluster is set up and the transformation is getting surpassed or anything, with the data set, basically the NoSQL, or you can say the Elasticsearch, or any NoSQL or unstructured databases, what happens, right? Basically, in unstructured, anyone can easily put unrequired data over there. Let\'s say the field name, home address is not over there, OK? And I don\'t want that in my database, OK? But if anyone tries to put that data, it will for sure store that, because it\'s unstructured data. For that, what we have done is we have created a template, OK? What is a template? What kind of data should we put into that index? Or it will be defined into that template. And we have mapped it as a strict. Mapping should be strict, OK? Then only, whenever the data being pushed to that index, we will for sure, every time, check that if the data is in correct format or not, OK? That\'s how we maintain the data integrity in our database and the storage is healthy. So yeah.\n','I would like to share an example of a challenging data transformation and storage problem I recently encountered while setting up Elasticsearch with Kubernetes. One significant challenge was the need for a local SSD to ensure faster data retrieval, as EBS volumes were not suitable for our requirements. We had to create a storage class for local SSDs, which Kubernetes does not provide by default. To address this, we utilized a third-party solution called OpenEBS, which allows us to provision local storage.\n\nHowever, mounting SSDs across multiple virtual machines proved to be another challenge. We had an auto-scaling cluster with varying numbers of machines, making manual mounting of SSDs impractical. To streamline this process, I wrote a script that automatically identifies and mounts SSD storage on each node whenever a machine is launched.\n\nAnother issue we faced was maintaining data integrity in NoSQL databases like Elasticsearch. Since unstructured data can often lead to the storage of unwanted fields, we created a template to define the data that should be stored. We enforced strict mapping to ensure that only data in the correct format was allowed.\n\nBy using OpenEBS for local SSD storage and implementing strict templates for data integrity, we successfully resolved these challenging storage and data transformation problems.','7','Bhushan\'s response effectively describes a complex problem he encountered with Elasticsearch storage on Kubernetes and how he solved it by creating a storage class with OpenEBS and writing a script for SSD mounting automation.

Can you please discuss the approach you took to improve performance and reduce costs?','Yes, for sure. I have explained that about modernization in my pipelines. So first thing is like why we are modernizing our pipelines. First thing is like a cost optimization. Second is like for the performance that we have and third is like a further scalability. Right now we are using Lambdas, we are using Polars, we are using Kinesis. That is totally based on the AWS managed services, okay, and those are really, really, very costly. So what we have decided, we will use Kafka, that will be a self-managed Kafka cluster. Okay, we will ask our customer to put the data, a lot of data Kafka can handle. It can be easily scaled to a different, different level with minimum price and whenever it\'s not required, we can scale it down. Okay, now coming to the cost optimization, now coming to the scalability first. Okay, now consider there are like 400 Lambdas are working for the one kind of a data, let\'s say for the print, there are 400 executors on the Lambda are working parallelly or concurrently at a time. So for each 400 processes, you have to pay for them for sure, because Lambda works, Lambda is a serverless technology and AWS is asking for the money for each execution or each Lambda getting triggered. Okay, so that\'s how the AWS is making money. But sometimes what happens like we don\'t need to pay that much money because sometimes we need those data to be processed much faster and in a much efficient way. So we have to pay more money for it and sometimes it\'s like, it\'s very like we don\'t need to, we need those Lambdas and all these things to be processed and executed fast. This totally depends on what kind of a stream it is. Okay, so what we need to do is like, what we have done is like we have used Kafka, we have used Apache Beam and we have modernized pipeline, we are using Kafka, from there we are using the Apache Beam pipelines. Okay, what we will do, here we can set manually or you can say the based on auto scaling policy policies that we will set up. Okay, we can scale the executors required however we want. Okay, let\'s say you have received 10 GB of data in a morning. Okay, and you want that to be processed very fast right now. Okay, and with the less amount of money, you can easily create a replication factor, replication of that particular parts to 100 to 500 to 1000 at a time and that does not affect much cost to you because you are going to pay for the, you are going to pay for the machines that has been used. Okay, and that machine will be for sure cheaper in terms of Lambda. Okay, and that executor will continuously work whenever the data goes down or whenever the data flows come to down, you can easily scale it down. So, it will be faster processing as it\'s a big data technology, it will process your data in a much faster way. Okay, there will be cost optimization and then we are also handling the scalability with the help of Kafka and the executors. So, that\'s how we are doing. Okay.\n','We have taken a proactive approach to modernizing our data pipelines at Onclusive, emphasizing cost optimization, performance, and scalability. Initially, we relied on AWS managed services such as Lambdas, Polars, and Kinesis, which proved to be quite expensive. As a result, we transitioned to a self-managed Kafka cluster, which is both scalable and cost-effective. Kafka can handle large volumes of data and allows us to adjust our capacity as needed.\n\nTo further optimize costs, we replaced many Lambdas with Kafka and Apache Beam. Since Lambdas operate on a pay-per-execution basis, they can become costly when running multiple instances simultaneously. With Kafka and Apache Beam, we can implement auto-scaling policies that enable us to increase the number of executors when demand rises and decrease them when it falls. This flexibility significantly reduces our expenses.\n\nFor instance, if we receive 10 GB of data in the morning, we can scale up the executors to process this data quickly. As the data flow decreases, we scale down accordingly. This strategy is more economical than maintaining numerous Lambdas.\n\nIn summary, by leveraging Kafka and Apache Beam, we have enhanced performance, reduced costs, and ensured scalability. Our modernized pipelines are now efficient and cost-effective.','7','Bhushan\'s response outlines the reasons for modernizing data pipelines, focusing on cost optimization, performance, and scalability. He explains the transition from AWS managed services to a self-managed Kafka cluster and the use of Apache Beam. However, the response could be more concise and better structured, highlighting the key steps taken and the impact on cost and performance. Bhushan could improve by providing specific examples of cost savings and performance improvements, as well as detailing the decision-making process behind choosing Kafka and Apache Beam, as seen in the benchmark response.'),(427,69,35,413,100,'How have you incorporated open telemetry into serverless AWS Lambda for failure analysis, as mentioned in your experience with Onclusive?','So, open telemetry was one of the POC project that I have done, I have given a task to check the flow. So, there is a lambda layer that we have to add for the open telemetry. So, once we add that layer, we will get something as a telemetry graph, we have for that we have added and from there, we can check where the data is going, where the points have been connected, how the architecture is accessing data points from one point to another point, we will get all those details with the open telemetry lambda layer, and that was just a POC project basically, I did it, but that was not been in production, because it was again costing and all those things. So instead of that, we have started using the consumption logs that we push to the Kafka topic and it will be much easier for us to do that. So, for the lambda or the open telemetry thing, we are just doing that for the POC basically. So, it was not much, it was useful, but it is costing is used very high, so we have stopped using that. So, yeah. \n','I integrated open telemetry into serverless AWS Lambda as part of a proof-of-concept (POC) project. We developed a Lambda layer for open telemetry, which produced telemetry graphs that allowed us to monitor data flow and interactions within the architecture. Open telemetry revealed important details about data points and connections, which were beneficial for failure analysis. However, the associated costs were quite high, making it impractical for production use. Consequently, we decided to send consumption logs to Kafka, which proved to be a simpler and more cost-effective solution. While open telemetry provided valuable insights, we chose alternative methods due to budget constraints.','6','Bhushan\'s response indicates that he has experience with a proof-of-concept project using open telemetry in AWS Lambda, but it was not implemented in production due to cost considerations. He mentions the use of a Lambda layer for telemetry and the decision to use consumption logs with Kafka as an alternative. However, the response could be improved by providing more detail on how open telemetry contributed to failure analysis during the POC and discussing the specific insights gained from the telemetry data. Additionally, Bhushan could articulate the cost-benefit analysis that led to the decision not to proceed with production implementation, as demonstrated in the benchmark response.'),(428,69,35,413,100,'Can you please tell me about a time when you had to work closely with a team to overcome a significant challenge in a project, and how did you ensure effective collaboration?','Okay, so I have been recently working on the Elasticsearch migration from OpsOrts to Kubernetes. So for that, we for sure needed the help from the, I was from the development team, one person was from the DevSecOps team, then one head was there who was the architect, okay, and one more person who is working as a DevOps team. All of these, I was managing this, okay, managing this in terms of like having those details how our cluster needs to be set up, all the requirements needs to be set up and also I was primarily working as a development team for the development of any services or any kind of health charts and all those things. So I was managing this communication from in the point of setting of the meetings, building them, I have created a channel and the group on the slack, okay, for whatever the communication and the decided factors for the technical factors, we can, I will push over there, okay, all the documents will be kept in the node format, all the documents each day I have been creating at the end of the day and circulated with the team so that next day they will be able to get the documents, whatever we decided and whatever we have gone through and whatever challenges we faced, all was kept in the documents in the form of JIRAs as well, basically we are managing all the project based on the JIRA, we created a ticket, we created separate project for them basically, so all those tickets were maintained, we were used to have a, it was like a fast and required project, it was an urgent project required, so we were focussing working on from like 6 months on that, so we usually kept a meeting in the morning and a meeting in the evening, also I was closely working with an architect, solution architect to find a different kind of solution, so basically the key factor of all the communication was JIRA, meetings and the slack channel or you can say the teams we were using, so we were using all the communication media for our communication purpose and basically the calls, so that\'s how we manage the project, the complexity of the project was too high, let\'s say if I am facing that issue related to that storages, for that the carpenter that is autoscaler at our end, so we need some help from a DevOps side to understand what kind of a challenge is they are facing to mount that issue, for that DevOps person would not be helpful, I need to write a script, because all of these entries, identities does not work independently, they are integrated to each other, for some of my requirements, I am dependent on DevOps team to spin up the load, because it\'s their job and I cannot handle that or the Terraform script and all those things are required, as a developer, as knowing to the code, code based side, I was known that this code needs to be there when it triggers the EC2 machine that needs to run to mount that SSD, so that was my task, I have to collaborate with them how we can run this based on how when the machine is been triggered, so that\'s how we collaborated everything and all the communication will be on the calls, even though as being a remote team, we have maintained doing that in a very efficient way, so yeah, so basically that\'s how we managed all the projects.\n','I worked closely with my team to overcome a significant challenge during our recent migration from OpsOrts to Kubernetes on Elasticsearch. Collaboration was essential to our success. \n\nThe development team, DevSecOps, architects, and the DevOps team were all actively involved in the process.

Each day, I circulated notes and documents, and we used JIRA to track tasks and progress.\n\nWe held morning and evening meetings to address the urgent and complex nature of the project. I collaborated closely with the solution architect, and together we explored various solutions.\n\nKey factors for effective collaboration included JIRA, meetings, Slack, and calls. We effectively managed dependencies between teams; for example, the DevOps team assisted with auto-scaling and storage issues, while I wrote scripts for EC2 machine triggers.\n\nEven as a remote team, we maintained efficient communication. By organizing meetings, documenting decisions, and utilizing collaborative tools, we successfully overcame the challenge.','6','Bhushan\'s response illustrates his role in managing a complex project involving the migration of Elasticsearch to Kubernetes, requiring collaboration across multiple teams.
