Mostly telephonic and video call interviews since I am from a different city.

Interviewers are asking mostly about multithreading and design questions.

There are 2-3 rounds before you get into the managerial round.

More focus on core Java and design-related questions.

1. If you get 1000 requests for your API, but your hardware can handle only 200, how can you handle the load?

2. Design connection pooling.

3. Design a JSON parser similar to Jackson.jar, which was used in my project.

4. How do you handle an OutOfMemoryError in production?

5. Explain ConcurrentHashMap.

6. Design your own load balancer.
