Varun's response is unhelpful as he admits to not knowing how to handle the situation, which reflects poorly on his problem-solving abilities and readiness for the role. This lack of insight is particularly concerning given the complexity of the question regarding cart abandonment rates. In contrast, the benchmark response provides a comprehensive, systematic approach to addressing the issue, demonstrating analytical thinking and a proactive mindset. To improve, Varun should prepare for potential scenarios and develop strategies based on his experience. He could have articulated a plan similar to the benchmark response, showcasing his ability to analyze data, gather customer feedback, and iterate on solutions.
