Varun's response is abrupt and lacks engagement, as he simply states that he has no questions and is ready to end the call. This approach may come across as disinterest or a lack of preparation. In contrast, the benchmark response demonstrates professionalism and appreciation for the interviewer's insights, while also leaving the door open for future communication. For improvement, Varun should consider expressing gratitude for the opportunity, acknowledging the information shared during the interview, and indicating openness to follow up with questions later if needed. This would reflect a more positive and engaged attitude.
