Interview Round: Technical Screen
Build a React single-page application for a parking lot attendant. The lot has a configurable number of spaces, and each space has a type such as compact, regular, or large. The UI should show current occupancy, allow a vehicle to check in, assign the nearest compatible available space, allow check-out, calculate the parking fee from the entry and exit time, and display a history of completed parking sessions. Keep state in the browser; no backend is required. Use functional components and hooks, and make the design easy to extend with new pricing rules or vehicle types.
Quick Answer: This question evaluates proficiency in React-based frontend engineering, including single-page application architecture, state management with hooks, component design, domain modeling for vehicle and parking-space types, nearest-compatible space assignment, time-based fee calculation, and extensibility of pricing rules.
