About the Stripe Backend Engineer hiring loop

Stripe runs uniquely long onsite loops (4-6 hours), with a heavy emphasis on integration-style coding rounds (build a working API client end-to-end) over LeetCode puzzles. System design covers payments-grade reliability. Behavioural rounds anchor on "Stripe values".

Backend rounds score on API design quality, database-tier reasoning, scalability anchoring, and operational maturity (observability + reliability). Trade-off articulation differentiates Senior from Mid.
