Pros

Google is a great place for a computer scientist. There are large problems that need to be solved at enormous scale. Engineers are treated with huge amounts of respect and are listened to in regard to improving productivity and removing redtape. Google has great benefits like free food. I've forgotten how to make my own lunch.

Cons

Unfortunately Google is a big company, so there's always red tape. How much you have to deal with it depends on which group you end up in. It can be hard to see how your project fits into the grand scheme of thing given how big the company is now.

Advice to Senior Management

Why do I have to offer advice to management? Meh, I can do that internally. Google has plenty of avenues to talk to our bosses.
