Varun's response outlines a general approach to implementing a predictive analytics solution, focusing on tying inventory levels across channels and using historical data for predictions. However, it lacks the depth and clarity of the benchmark response. While he mentions important aspects like inventory management and historical demand, he does not provide a comprehensive view of how to integrate technical and business perspectives effectively. Additionally, his statement about not being technical undermines his credibility in discussing predictive analytics. For improvement, Varun should aim to articulate a more structured response that includes specific technical methodologies, collaboration with stakeholders, and how the solution aligns with business objectives. He should also express confidence in his ability to discuss both technical and business aspects of the problem.
