Varun's response, "Let's conclude," is abrupt and lacks the professionalism expected in an interview setting. It does not express gratitude or interest in the opportunity, which could leave a negative impression. In contrast, the benchmark response is courteous and expresses appreciation for the interviewer's time, while also indicating a willingness to continue the conversation in the future. To improve, Varun should aim to convey a more positive and professional tone, thanking the interviewer for the opportunity and expressing interest in future discussions. For example, he could say, "Thank you for the opportunity to discuss my experiences, and I appreciate your time. If there's a chance to continue this conversation later, I would be very interested."
