They believe in group think and total transparency. Screening interview was recorded as were all of the face to face interviews. Was told to read, study and be prepared to discuss the 100+ page "principles" document from their web site. They don't care what you know, who you know, what you've done - they care about how you think. Be prepared to answer questions from first-principles. Not surprising, as I was interviewed by early-20-something Hardvard grads with no experience but big chips on their shoulders. Not a good place for senior/experienced managers - probably a good place for keen & green college grads.
