Customer and User Obsession Questions

Demonstrating a deep commitment to understanding and advocating for customers and end users. Candidates should show how they prioritize user needs in decision making, even when it conflicts with other priorities, and provide concrete examples of advocating for users internally. Topics include using qualitative and quantitative research to surface user pain points, validating assumptions with user evidence, designing or improving experiences to solve real problems, maintaining ongoing connection to users through feedback loops, and influencing stakeholders to keep the organization user focused. Examples may range from entry level empathy and direct customer learning to strategic changes driven by user insight.

In Python, implement a function that ingests two iterables: predictions and feedback. Each prediction is (user_id, item_id, pred_label, pred_prob, timestamp). Each feedback is (user_id, item_id, true_label, timestamp). Compute per-user precision and recall for a binary label over the last 30 days. Assume streaming batches and limited memory; describe any approximations you make.
