This question evaluates product leadership, product analytics, experimentation, and impact-measurement competencies for a Data Scientist, emphasizing problem framing, metric definition, trade-off reasoning, risk mitigation, and the ability to quantify and communicate end-to-end results.

Walk through the most impactful product you led end-to-end. Be specific: (a) initial problem framing and target metrics with baselines and explicit goals, (b) the alternatives you rejected and why, (c) the riskiest assumption and how you de-risked it with data or prototypes, (d) exact impact achieved (e.g., +3.2% 7-day retention, +$X/week revenue) and confidence intervals, (e) how you handled a major setback (e.g., an experiment backfired), and (f) what changed in the org as a result (processes, roadmap, staffing). What would you do differently if you had to ship it again under a 50% smaller team?
