Varun's response, "I don't know," reflects a complete lack of engagement with the question and indicates a significant gap in relevant knowledge regarding strategies or tools for enhancing efficiency in e-commerce supply chains. This response fails to provide any insights into his capabilities or understanding of the role's requirements. A more constructive approach would have involved discussing any general strategies or tools he might be aware of, even if he had not applied them directly. For improvement, Varun could have said, "While I may not have specific examples, I understand that leveraging data analytics and automation are key strategies for enhancing supply chain efficiency, and I am eager to learn more about these tools."
