I used to go to a bar in Santa Monica (Warszawa) where the Google folks go every Friday for happy hour. The recruiters kept trying to get me to apply, but I never did. I get the impression that they want people with Engineering/CS backgrounds and here I am a programmer with an English degree. I bet I'd have a better chance of building a startup and selling it to Google so that I could work there than going through the application and interview process. I could be wrong though...
