Varun's response is minimal and lacks engagement. While he acknowledges the question, he does not provide any detail or warmth that would typically be expected in a professional interaction. A more effective response would include a polite greeting and a brief elaboration on his day, fostering a more conversational atmosphere. For example, he could have said, "Hello Avi, it's a pleasure to meet you. My day has been going well, thank you for asking. How about yours?"
