AI-Assisted Coding Interview Questions
Medium Scenarios
2 challengesConcurrent Eviction Cache
Implement a bounded cache with recency-based eviction, then reason through thread safety, race conditions, and production hardening.
Delivery Payment Ledger
Build a driver payment ledger in three phases: exact delivery costs from hourly rates and start and end times, payouts that never pay a delivery twice, and a 100,000-delivery performance tier.
Hard Scenarios
4 challengesAirfield Operations Controller
Design and implement a small airfield scheduler that sequences takeoffs and landings while handling runway conflicts and changing priorities with help from an AI assistant.
Gated Maze Pathfinder
Fix defects in an existing maze-routing codebase, build a shortest-path search that respects one-way gates, then make it fast enough for mazes of up to a million cells.
Unique-Letter Word Picker
Fix defects in a small word-game codebase, write an exact search that picks words sharing no letter for the largest total length, then make it fast on large word lists.
Warehouse Robot Grid Navigator
Build an extensible warehouse navigation service, then evolve it from one robot to multiple robots with collision handling.
