Ask HN: I was just acquired by Google. What should I expect?

The startup I work for (Apture) was just bought out by Google. On one hand, I'm excited. I have heard nothing but good things about how they treat their staff, especially engineers. On the other hand, there's no way to go from working for a company with 12 people to a company of 60,000 people and not be a bit overwhelmed.

Can someone hear give me an idea of what to expect? Are there any habits I may have to break? How does the Google Experience tend to be different for "acquired" engineers versus "hired" engineers?
