1. Design a rate limiter - I already read this question still I failed because the interviewer was asking me things I did not know about 2. Coding - this round went very well because the coding question I had already seen. Word Search 2 from leetcode 3. Order processing or checkout system - LLD failed this round, was expected I know all SOLID principals in implementation

There were 4 rounds. I got rejected in the first round itself with no feedback from the HR or anything. Bad experience because of HR ignoring the time slots I chose and I was a bit dizzy during interview and blabbered unnecessary stuff.. Also the lack of feedback after the interview.
