4 Rounds: 1 Recruiter Screen, 2 technical rounds, 1 Hiring Manager Round. Overall a great interview, they valued familiarity with the company, and thought process over correct answers directly, it was more of a valid discussion on system design than one right answer.

Interviewers were very polite and helpful. Repeatable questions on different interviews, which is a minus. Too much bureaucracy in interview process. Long response times from recruiter when I asked questions.
