The interviewer was visibly exhausted, which made the whole thing feel a bit flat.
Start by clarifying requirements and constraints, then outline a high-level component architecture and state management strategy. Focus on scalability, real-time updates, and trade-offs between different approaches, while demonstrating React best practices.
Pro tip: Emphasize how your design handles real-time updates and scalability, as Uber deals with high concurrency and dynamic pricing. Mention using WebSockets or server-sent events for live parking spot availability, and consider edge cases like concurrent bookings.
Ask questions to understand the scope: number of floors, spots per floor, vehicle types, pricing model, real-time updates, and user roles (driver, admin).
Design the data structures for parking spots, vehicles, and bookings. Decide on state management (Context, Redux, Zustand) and how to handle real-time updates.
Break down the UI into reusable components: ParkingLot, Floor, Spot, Vehicle, BookingForm, etc. Consider routing and lazy loading for performance.
Discuss optimizations: virtualized lists for large lots, memoization, code splitting, and efficient re-renders. Consider backend integration and real-time sync.
Compare approaches (e.g., optimistic UI vs. server confirmation), handle concurrency, offline support, and error states. Mention testing and accessibility.
