There was a phone interview first. He just asked me my project experience and all the languages and libraries used. My expertise on them. On the second round, they called on site. They gave me a laptop loaded with Eclipse/Java loaded on Ubuntu. The interviewer asked to put function which can calculate if the word is a pallindrome or not. 45 min test. The third round was on the same day. A group of five people have asked me question for 30 mins.
