Googlers have been Olympic athletes and Jeopardy champions; professional chef and independent film makers.
The chief operations engineer is also a licensed neurosurgeon.

Googler engineers all have “20 percent time” in which they're free to pursue projects they're passionate about. This freedom has already produced Google News, Google Suggest, AdSense for Content, and Orkut – products which might otherwise have taken an entire start-up to launch.
