Process was to build Othello in an hour and then if you pass that you get specific questions from the engineering team you're applying to or suited for. If they're satisfied with everything they make the offer on the spot. They didn't send me any preparation materials and then tried to reference those materials when I came in for my interview. The interviewer said it was common for them to mess up since they're changing their process and interviewing so many people. They entire building felt like a "coding" sweat shop and the culture sucked, and the one interaction I had with them was very negative in being forgotten.

I guess I would only add that they apparently haven't updated their interview process in anyway from those posted most recently to mine. Same questions, same order. I guess if you really want an offer from this company just memorize those answers. Talking with the engineers didn't give me a sense of this being a great place to work and this process felt like a waste of everybody's time.
