I had 4 interviews. First with the recruiter which was very formal. Second with a team member in a technical round. The third and fourth were 1 hour long continuous zoom calls. Be thoroughly prepared with control system concepts like Consumer-Producer, Paging, Memory, and many more.

It was quite lengthy but a bit easy. The process contained 4 rounds. Two were technical rounds and the later two were mangerial. The questions asked were of medium level and were pretty standard.
