Give a concise overview of your background in e‑commerce risk control (30–60 seconds). Then: (1) Why do you want to join our e‑commerce risk team specifically, and why now? (2) What are your top three goals for your first 30/90/180 days, and which concrete metrics will you use to measure success (e.g., approval rate, chargeback rate, coupon‑abuse rate, manual‑review SLA)? (3) Describe one time you pushed back on a risk policy or threshold: what data did you use, what trade‑offs did you quantify, and what was the outcome? (4) If offered competing projects, how would you prioritize them given limited analysts and a 10% engineering allocation?
