The most arrogant interviewers I ever had in Silicon Valley. The questions/problems were reasonable and pretty standard for similar companies, no surprises there (my interview experience: I was interviewed and got offers from VMWare, Google, and some other companies). One of the interviewers raised voice at me a couple of times, another one was showing his disrespect through the whole interview. Two other interviews were ok. If you get an offer from them, I would definitely recommend further checking of the team health.
