Varun's response is friendly and shows enthusiasm for the interaction, which is positive. However, it lacks depth and does not provide any specific details about his day, which would have made it more engaging. An ideal response would include a brief mention of a productive task or experience from his day, demonstrating his ability to reflect on his activities. For improvement, Varun could have said something like, "I've been working on a project that involves optimizing our digital marketing strategy, which has been quite rewarding."
