Round 6: Product Sense (Structure Your Answer)

26. "How would you measure success of a search feature?" Use GAME. - G: Reduce time to find what users want, increase actions from search - A: Type query → see results → click result → complete action - M: Primary — search-to-action conversion. Secondary — zero-result rate, avg result position clicked. Guardrail — page load time, user satisfaction - E: High clicks but low conversions = results look relevant but aren't. Track post-click behavior.

27. "Revenue dropped 15% this quarter." First 3 things you do. (1) Clarify: vs last quarter or YoY? All segments? (2) Decompose: Revenue = Users × Conversion × AOV — which dropped? (3) Check internal (deployments, bugs, logging changes) before external (seasonality, competitors).

28. Estimate: How many data scientists work in Chicago? ~5,000 companies with 500+ employees in Chicago. Maybe 30% have DS teams averaging ~5 DS each. 1,500 × 5 = ~7,500. Plus smaller companies and consultancies → maybe ~10-12K. (Rough but defensible.)
