Total of 3 rounds were conducted. The first two rounds went on fine.But when it came to low level design round, the interviewer was quite uncooperative. The requirements were not correctly offered to begin with. And then during the solution, additional requirements were given and I was asked to assume more requirement from my side. There was very little contribution towards low level design, and more towards high level design. The interviewer had an attitude problem, and wasn't ready to listen to the design I was proposing. There was a fixed answer in his mind, and you can't go beyond those boundaries. Later on when I discussed this feedback with the HR, I was made to wait for a week saying we will do another round of low level design, but HR came back with the feedback that the interviewer wasn't completely convinced with the design. Completely unprofessional and careless attitude towards interview. Last minute cancellation and rescheduling has happened for round 2&3
