There were three rounds of technical discussion, which included a client round as well. Each round was from 30 to 45 minutes, and the interview was crisp and clear.

The questions were mostly based on the collections part, garbage collection, and how heap memory can be optimised. They also covered how concurrency can be handled using multithreading, like ExecutorService and ScheduledExecutorService.

The questions were related to real-world scenarios, such as a book ticketing system in BookMyShow and Paytm wallet creation and updation.
