Worst experience so far. Team lead shared the screen after saying Hi and asked me to implement below requirment in only 40 minutes. 1. **Requirements:** - Implement a VehicleTracker service with methods to: - Register a vehicle by VehicleID. - Update the vehicle's current location (latitude, longitude) and status (e.g., "In Transit," "Idle," "Maintenance"). - Retrieve the location history for a specific vehicle. - Calculate the distance from a specified vehicle to all other registered vehicles, using their most recent locations. - Retrieve a vehicle's current status and location. - Design the classes to store location history by vehicle, with each update timestamped. 2. **Assumptions:** - The system does not require persistent storage (an in-memory solution is sufficient). - Implement async/await methods for eventual conversion to a database instead of in-memory storage. - Assume each vehicle will send location updates periodically. - Distance calculation can use the Haversine formula for accuracy based on latitude and longitude. 3. **If time permits:** - Add unit tests for the main functionalities, especially for distance calculations. - Implement a way to filter location history based on a time range.
