Varun's response is missing, which leaves a gap in his engagement and professionalism at the conclusion of the interview. Not responding at all in this context suggests a lack of interest or awareness of the importance of closing an interview on a positive note. In contrast, the benchmark response expresses gratitude, acknowledges the opportunity, and conveys anticipation for the next steps, which is essential for leaving a good impression. To improve, Varun should always ensure he concludes interviews with a polite and appreciative response, reinforcing his interest in the position and maintaining professionalism throughout the conversation.
