This question evaluates systems thinking, root-cause analysis, metrics-driven decision-making, and cross-functional leadership in operational product-process contexts.
Behavioral / Product-Process Scenario
You work on a food delivery platform. Customers sometimes receive the wrong items (restaurant packed incorrectly, driver picked up wrong bag, labels missing, etc.).
Prompt
Explain how you would maximize the reduction of wrong-order incidents. Cover:
- How you would diagnose root causes (restaurant vs driver vs app flow)
- What process and/or technical changes you would introduce
- How you would measure success and manage trade-offs (time at pickup, cost, merchant friction)
- How you would roll out changes safely
