Really? I went through the Google interview process back in 2006, and I had a fantastic time. The level of transparency was a little frustrating, but everyone I was in contact with was polite and responsive, and I never found myself waiting for replies. The on-site interviewers were really fun to talk to, and I left with a great impression.

But I wouldn't call the process significantly better than anywhere else. I've had plenty of other interviews on par with that, some better, some worse.
