4 rounds. round 1 with recruiting manager. Very professional, clear with communications and responsive to questions. Round 2 with Principal engineer - technical+ scenario based QA for 1 hour. Round 3 with design team - complete focus on UI and non UI automation skills along with matching exercises for 1 hour. Round 4 with VP of engineering. Technical discussion, past projects explanation, coding exercise. (1 hour). All rounds and all interviewers very professional, humble and non pushy. they allow you to think and answer.

Very structural. There are 3 rounds after call with HR. And every round I would say pretty complicated. But interviewers are very professional and you don't have a feeling that they try to brake you.
