So I have given 2 Technical round followed by 1 Manager round and 1 HR round. Technical Expectations was very high during each technical round. For each round including HR round panel of two person was there. Each round was for more than 1 hour. I have given 2nd round for 1 hour and 45 min. One should have good technical knowledge in order to clear as Questions are based on real world technical issues and one should have understand the Root Cause.
