Initial communications were friendly, the invitation to interview seemed quite informal as it was directly with the department and not HR. The interviewers were welcoming and made me feel at ease when I visited the office. The offices are amazing, but everyone was very young with good looks - seemed somewhat pretentious. Apart from my superficial judgement, I felt that my interview went very well and that I made a good impression. It was quite disappointing to never hear back - not even a courtesy rejection email. Would have expected better from such a big name.
