Varun's response is brief and lacks the professionalism and engagement expected in an interview setting. While it's acceptable to have no questions, a more polished response would acknowledge the interviewer's efforts and express appreciation for the opportunity to ask questions. The benchmark response demonstrates a courteous and professional demeanor, indicating that the candidate values the conversation and is open to future communication. Varun should aim to convey a more thoughtful and respectful tone, even when he has no questions.
