Very friendly culture, incredible access to practically all of company information, great people to work with and learn from. With thousands of users every second, almost nothing is trivial, so work tends to never be boring. The work process is very professional. Of course, just getting to build stuff on Google's awesome infrastructure (both hw and sw) might also be considered to be interesting :)

If you are an engineer, it's wonderful. The place is built by engineers, for engineers. The company's rules, structure and processes usually make sense, and when when they don't, anyone can fix them, if they can get enough people to reach a consensus. Promotions sometimes seem very difficult - but well earned, and very fair.
