Design a car rental domain model covering vehicle categories and vehicles, branches, customers and drivers, a rental date range, rate-based quotes, reservations, pickup rental agreements, and return inspection with extra charges — preventing overlapping rentals of the same vehicle.
Design a car rental system: customers get a quote and reserve a vehicle category for a date range, pick up an assigned vehicle, and return it with an inspection that may add charges for mileage, fuel, or lateness. No vehicle can be double-booked for overlapping periods. Start by clarifying scope and the core objects.
Work in the provided coding workspace while explaining your decisions to the live interviewer. Validation may use inline tests, examples, comments, or a verbal walkthrough.
Practice this problem in the live coding workspace while the interviewer probes your clarification, implementation, trade-offs, and validation.
