DoorDash — Merchant, Ads & Sales — Product Case Questions

Role context: Data Scientist, Merchant/Ads & Sales Analytics · Est. study time: 35 min · 3 questions

How these map to the role

These are merchant/ads cases: an ambiguous monetization or merchant question you frame into metrics and a measurement, and a recommendation you defend. Two things recur — ad value is incremental (not attributed), and monetization trades against consumer experience and merchant retention.

Each answer is a coaching walkthrough: a Sample answer (clarify → approach → a simulated back-and-forth → a clear call), then a Deep dive with illustrative example, then a Grading rubric.
