1. Initial technical phone interview - coding with a shared document. Followed by 4 more technical interviews - again, coding with a shared document, with different interviewers. The last interview is with the team manager.

The interview process was very smooth but difficult. The interview itself was hard because of the interviewer's thick accent. The recruiter was super friendly and accommodating; I felt like they wanted to hire me.

Two first-round interviews and an additional one, since I blew up one of the first two. The third one is slightly harder; however, I think I solved it but failed to provide an optimized solution based on the problem's properties.
