Varun's response is missing, which leaves a gap in the evaluation. However, based on the benchmark response, it is clear that an ideal closing statement should express gratitude, appreciation for the opportunity, and anticipation for the next steps. A suitable response from Varun would have included these elements to leave a positive impression at the end of the interview. For improvement, he could have said, "Thank you, Avi! It was a pleasure speaking with you. I appreciate the opportunity to discuss my experiences and look forward to hearing about the next steps in the hiring process."
