The first round was a written one, with two questions on a sheet of paper. I had to write the solutions.

We had to wait for about two hours to get the answer sheet evaluated.

After that, there was a one-on-one face-to-face round, after which I was told to come back after two days for the next set of rounds.

After two days, I had two more face-to-face rounds. The duration of the wait between rounds was, on average, one hour. The HR told me he would give feedback after consulting the panel.

There was no feedback in the subsequent days. I even tried reaching him, but he always hung up on me.
