Uber Interview Question Bank
Uber's loop leans heavily on Uber Eats and rider/driver marketplace problems — Cart pricing, geo heatmaps, surge, and restaurant recommendation surface in nearly every onsite at L5+. Coding rounds are mostly tagged LeetCode patterns, but Hack2Hire OAs ship a small rotating set of original problems that rarely appear elsewhere. Coding bar is the gate; system design quality drives leveling between L5a / L5b / Senior / Staff.
