Your question is Design an Elevator Dispatch Ranker. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
You are building the decision system for a bank of elevators in a multi-floor building. The system observes hall calls, car positions, load, direction, and recent traffic patterns, then decides which elevator should serve each request.
How would you design an elevator system?
