It has now been one month (and two days) since I started working at Google.
So far this has been a great experience! Working on a really impressive infrastructure, with a lot of great people and in a very friendly environment. I can not describe anything about how great are some internal processes or technologies, but if you have the opportunity, I definitely encourage you to come working with us and see by yourself.
After two weeks in Kirkland, I will fly to Mountain View tomorrow for a week, don't hesitate to contact me if you are around. (Update It seems I'm staying about 2 minutes walk from Mozilla address, don't know if there are many people there)
