I was one of the best experience I ever had. I reached Fidelity around 9:30 AM. Then HR person escorted us to the conference room. We were served snacks and tea. Then around 10 AM, Interviewer called me. He was a very professional and knowledgeable person. He first started asking me what I know. He was side by side writing the same on a piece of paper. Then the interview started. All questions were based on multithreading, so prepare well. The main thing is how confident you are. Then I was called for another round, I think it was managerial round. The interviewer asked about my professional life. He is a very good mentor. He gave me a problem and asked me to write the pseudo code on the whiteboard. Then he asked me for my previous projects. I cleared that round too. Then it came to the turn of HR, she asked for salary expectations. After 15 days of wait, I finally received offer letter. Yes, One thing more... They also served Food which was very yummy ;)
