First round was telephonic for me as I was staying in a different city then. Second round was the technical round, again telephonic for me because of the same reason upon special request.

Hiring manager round 3 rounds of technical 1 system design Leetcode hard questions in 2 interviews. Medium in another. System design related to things done at work. The whole interview process took around 2 weeks. I was not offered the position because I was not ready technically at the time. Interviewers were very helpful but questions were very tough
