My experience talking to Google wasn't tremendously positive; I did have to do a more-than-usual followup to move my candidacy forward. I don't know that I'd get too grumpy about it though; I had another experience with a major US tech firm at the same time which easily was 4x as long and required a great deal of pushyness to come to a resolution. Google came off as an "eh", but not "ugh clearly not a viable employer".

Remarkably, Microsoft was one of the fastest turnarounds I've ever had (only beaten by my current employer). I didn't expect it and I'm still impressed.
