Interview Question: Design a Ride Sharing API

The interview question is:

Design a Ride-Sharing API.

The main challenge is handling ride state and location updates that change at different rates.

A rider creates a ride before any driver has accepted it. A driver then moves toward the pickup, starts the ride, and completes it. Driver position changes much faster than the durable ride itself. The rider may lose the network between two updates, and a partner server may need the final outcome without holding a connection open.
