Problem

Scenario

You are designing the ML architecture for a ride-sharing application. Riders request trips, nearby drivers are considered, and the system must decide which drivers to surface and in what order so pickups are fast and marketplace efficiency stays healthy.

Question

Design a scalable architecture for a ride-sharing application.

What this tests

  • Candidate retrieval for feasible drivers
  • ML ranking and constraint-aware re-ranking
  • Online serving versus batch feature computation
  • Cold-start, feature drift, and fallback handling
