3 interviews total. Initial interview was just describing my background and what qualifications I have with a single company recruiter. Second interview was with the group manager. This one was slightly technical but mostly behavioral questions. Third interview was a technical interview in python and c++ with 3 senior managers. I had to share my screen and code in front of them for an hour.

There were rounds of technical interviews was asked about data structures and multithreading. Was asked about background from school and side projects and hypothetical situations when dealing with bugs. The interviews were roughly about an hour each. The interviewers seemed very friendly and was able answer any questions I had about the company.
