Seriously. If you search the right terms often enough, Google might interrupt your quest for knowledge with a question: "You're speaking our language. Up for a challenge?" If you are, you'll get access to Foo.bar, a UNIX-like interface that presents users with programming challenges. Foo.bar led Rosett through six different challenges, each with specific requirements and time limits. When he finished them all, it asked for his contact information -- Google rang him up, ran him through the regular employment rounds and now he works there. Simple as that.
Don't bother searching for Foo.bar though -- the test is invitation only. Finding the page is easy enough, but it won't let you play if you weren't specifically asked to: "To log in, you have to have logged in before," the page reads. Confused visitors are invited to, you guessed it, search Google for answers. It's a slightly creepy recruitment tool, but it's also fun, quirky and refreshing. Try it out. If you can.
