Round 1 - DS/Algo(1 hard and 1 medium LC) Round2 - LLD Round3 - hiring manager round discussion about past project and some behaviour and cultural question and HLD I aced all the round but still was rejected at the end. The feedback I got was I didn't have working exp on NoSQL DB and they were looking out for someone who had which I think is really stupid if someone hadn't come across a problem that required using NoSQL DB how can he work on that although I was pretty much able to describe in HLD round when &why which Db to prefer be it dynamo DB, mongo db or psql etc. Also, they had my resume from the start if they were looking out for someone having hands-on NoSQL they shouldn't have selected my profile at first. Try avoiding this company as much as possible you would be wasting your time interviewing with them
