A recruiter will contact you, and you will be given plenty of time to study. There will be three data structures rounds, one system design round, and one leadership round. If you clear these, there will be a hiring manager round.

Hair splitting... because they can. They have a strong market position and therefore a very deep recruiting pipeline. I doubt I failed at anything, but the feedback I got was very sketchy.

Open the door and go in to meet with some Indians. Then, finish the interview. It was an easy interview, but I failed due to being unprepared. I will try again next time.
