This interview is for a Senior Software Engineer on Coinbase's Consumer & Business Advanced Trading team, owning architecture for order management, execution engines, and reliability infrastructure behind the IntX product. Expect deep questions on distributed trading-systems design, multi-quarter cross-team technical leadership, and translating ambiguous product asks into scalable architecture. Strong answers show hands-on ownership of order management/execution/market-data/risk components, not just general distributed-systems experience.
