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.

The interview process was great and very professional. The recruiter was very forthcoming with any help that I needed along the way. The process consisted of a few interviews, with varying levels of difficulty.
