Swami's main weakness is the lack of depth in his responses. He often failed to provide detailed examples that align with the job responsibilities, such as in user acceptance testing and backlog management. His answers were sometimes vague and did not fully address the interviewer's questions, indicating a need for improvement in communication and interview preparedness. To improve, Swami could benefit from more hands-on experience in specific business analyst tasks and enhancing his ability to articulate his experiences and knowledge clearly and relevantly during interviews.
