The interview process was very long. It started with a formal HR round. Then, they called for a telephonic interview.

In the telephonic round, the main questions were from OOPs concepts, Core Java, and design.

After that, they conducted two rounds of technical interviews. In these technical interviews, they asked me to write code and solve some algorithms. Lots of questions were asked about data structures and design.

Overall, it was a good process, and they tested core skills.
