2 Rounds of Technical Discussions ( quite grilling i would say ) followed by One Technical Discussion with the Client and then a Manager's round followed by the HR Round. Because the customer was Really Technical , there was a good amount of preparation that was required .

The interviewer asked me what language was I proficient in? And I said Java. Then he started asking about Java. Some questions that he asked include some common algorithms,and something about data structure. And also he asked me to write a program using my own computer which I took with me to interview. Overall, Its good Process
