3 interview rounds. first one was system design, which was quite creative and fun to work through. supportive and positive interviewers, I managed to clear this round Round 2 was poorly organised. I was expecting a theoretical ML round but instead I had to face a live coding interview which threw me off. The question was a Leetcode Hard level involving dynamic programming, I reached a brute force solution but there wasnt enough time to refine it, leading to rejection. I applied regularly through google careers and my resume was shortlisted even though the role way suitable for holders of Masters degree or PhD ( I had only a bachelor degree and research experience at the time )

Standard interview. I was contacted by the recruiter and was matched with a team pretty relevant to my job. One phone interview, one fit chat, 4 rounds of onsite interviews.
