Conducted 3 rounds of interview performed good in all the rounds at the end i was rejected. one of the interviewer had no knowledge about the stack that it is required

It went smoothly. I had to give 2 rounds both rounds interviewer were friendly and we had a smooth process overall. The experience was very helpful and learning. In the first round they asked about basic introduction about my projects, then basic SQL and Linux questions. The second round basically tested my SQL queries my willingness to do the job and work in shifts.
