It started out as a low-level system desing for Multi-level, Multi-Entry and Exit Parking lot.

Design a system to be able to handle payments, parking lots in general, handling different types of vehicles, give a centralized view of the parking lots.

• Share the classes and the relation between them.
• Draw a class diagram.
• write an Algorithm to fetch the closest parking spot to the particular entry. Also while the vehicle exits point them to the closest exits.
• How will you handle multiple cars entering the parking lot at the same time?

From Low-Level design we switched to High-level on the same design that i shared.

• we discussed aspects of scalability, concurrency and sharding.
• How will you handle server requests?
• How many servers would you assign and how will you scale the system?
