It’s at Google. In the Creative Lab. And is usually for a year. You’d do real work, with real hours, and get paid real money. The food is free. Sometimes there’s risotto.
Previous Fivers have been writers, designers, filmmakers, technologists, and wild cards. (If you don’t know what a wild card is, play some Uno.)
You’d probably work with your fellow Fivers on some things and with lots of other Creative Labbers on lots of other things.
All you’ve gotta do is be brave and kind.
