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.

Pretty tough, but not too bad. It was a bit too all over the place. I'm not a fan of going back to the office. World-class problems to solve, and some of the problems they posed are just that.

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.
