Swami's main weakness is the lack of depth in his responses and the absence of detailed examples that demonstrate his expertise and experience. His answers were often superficial and did not convey a strong grasp of how to apply business analysis techniques effectively in real-world scenarios. Additionally, his communication was sometimes unclear and could benefit from more structured and polished delivery. To improve, Swami could focus on providing more specific examples from his past experiences that relate directly to the tasks and responsibilities of the role he is applying for. He should also work on enhancing his communication skills to convey his thoughts more clearly and professionally.
