Varun's response, "I don't remember," indicates a lack of relevant experience or knowledge regarding the identification and resolution of supply chain inefficiencies in the e-commerce sector. This response does not engage with the question and fails to demonstrate any understanding of supply chain optimization strategies, which are essential for the role. A more constructive approach would have involved discussing any related experiences or expressing a willingness to learn about supply chain management. For improvement, Varun could have said, "While I may not recall a specific instance, I understand the importance of optimizing supply chains and would approach it by analyzing processes and leveraging technology to improve efficiency."
