It was a three round interview and one HR interview. After clearing one interview, you will be eligible for another interview after getting mail and call. All interviews were held on the same day.

Had 2 interviews. The first one was a very straight forward interview. The interviewer asked me questions about Java and to explain basic OOP concepts, along with a very easy data structures question. The second interview didn't seem very relevant to the first and was a more behavioral type interview.
