Applied through a referral. Got a call from a recruiter right away, asking basic questions about background etc. He explained the process briefly and asked availability for machine coding round which was for 2.5 hours. Machine coding round - half an hour discussion of question, 1.5 hour coding (on my IDE with shared screen), half an hour demo and discussion of approaches + different design questions about additional requirements I wasn't able to finish all the requirements in the machine coding round question and so did not make it past this round.

There were 4 rounds in total 1. Machine coding round 2. DSA Round 3. System Design round 4. Hiring Manager Round Even after clearing all the rounds which i knew of HR suddenly told that HM feedback is not positive so they decided not to move ahead even though HM made me interviewed for 1.5 hrs and extended the interview which i know i would clear that.
