First technical round was quite easy. They asked questions on core Java and basic questions on Spring, Multithreading, Hibernate, Collections, and Serialization. One can easily crack it.

Second round was quite tough. The interviewer checked deep knowledge about Spring, Hibernate, Web Services, and Concurrency Control.
