The interview consisted of four rounds. I cleared the first round and subsequently received an email stating that the further three rounds were scheduled. After my second round, I was waiting for the third round to happen, which did not. There was no communication about this. I emailed HR, but there was no response. Finally, after a day, I received an automated email stating that I was not selected.

Ideally, if the rounds are meant to be eliminatory, candidates should be informed beforehand instead of scheduling all rounds and blocking their time, all without proper updates. This is pathetic.
