Technical round is bit on harder side, following is the typical stages but it may vary depending on one's performance. Initial telephonic screening. Then will be 4 rounds (30 mins each) Manager round and then HR discussion.

Interview was very technical in nature. Question level was not in very difficult range, but not in easy either. First interview was on phone with manager only. Second was on site with a bunch of engineers and was a lot more technical in nature. Brush up your technical knowledge prior to interview for sure.
