Design a Ticket Booking System

Design a web system for selling concert tickets. There is a database containing all seats available. You want to present them to users satisfying the following requirements: A users should be presented with 10 available seats at a time. The system prevents two users from being shown the same seats simultaneously. Users have a 2-minute window to select a seat from the presented options or request to see more seats. Requests to purchase a seat after the 2-minute window should be rejected. The system needs to be robust against users attempting to purchase seats they haven't been shown. When a user requests to see more seats, the system should not display seats that were shown previously.

Main focus was on the product experience at various inflection points of the product ( Eg: Reservation experience, Waiting queue experience, Real-time updates to the seatmap)
