I went through a three-level interview process: L1, an HR discussion, and L2, which was a client interview.

1. The L1 interview was a virtual technical round. You would be asked to explain your previous project experience, and the interview would be based on your skillset.
2. It took me roughly a week to get my L1 interview results. After clearing L1, I received a call from HR for a discussion.
3. Following the HR discussion, I had my L2 interview, which was an in-person interview at the client's location. The L2 interview had four rounds and was very difficult:
   • The first round was a coding round where you had to write down code.
   • The second round was more like a group discussion. You would be given a scenario and had to provide a solution.
   • The third round was a one-to-one discussion with the Technical Lead.
   • The fourth round was another one-to-one with what I believe was the manager. It was a technical interview.

My offer letter was released after clearing the L2 interview with the client. (The selection process may vary.)

Note: After clearing L2, I was selected and asked to take a mandatory online English Mocha Assessment before the offer letter could be released.

I was interviewed for the Java Spring Boot Developer role. My questions were mainly focused on:

1. Core Java topics (String constant pool, immutable classes, multithreading, exception handling, and similar concepts). The interview mainly concentrated on simple data structures and collection framework snippets.
2. Java 8 features (Lambda expressions, Stream API, functional interfaces).
3. Spring and Spring Boot features.
4. Hibernate.
