Got call from HR for the position and asked if I'm interested.
Rounds:
Total 4 technical rounds. No HR round.
Day 1: 2 Rounds of interview ( you can ask to schedule 1 round at a day Or 1 in morning and 1 in evening)
Day 2: 1 round
Day 3: 1 round
Clearing each round isn't mean you are getting selected in those rounds. It means you are eligible enough to not be rejected in each round particularly.
After all 4 rounds, all those interviewer will setup a meeting to discuss your positive and negative or week and strong area which also includes the behavior during the rounds. Then they all will decide to select or reject.
