About the Uber Backend Engineer hiring loop

Uber's system design is the headline round — real-time location services, surge pricing, dispatch algorithms. Coding rounds are LeetCode-medium. Behavioural rounds anchor on the "Uber values" (refreshed in 2022) — Customer Obsession, Build with Heart, Stand for Safety.

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