Varun's response mentions the development of a complex data pipeline and the challenges faced with company-specific features and database adjustments. However, the response lacks specificity regarding the use of Microsoft Azure or GCP services, which was a key part of the question. Additionally, Varun could have elaborated on the technical solutions to the challenges mentioned. To improve, Varun should detail the cloud services used, describe the architecture of the pipeline, and explain how he addressed scalability and flexibility, as demonstrated in the benchmark response.
