If you are looking for at job at Google, all you have to do is search.
Google can have so much fun with their index. They can present whatever they want, make special searches return special results etc. I often wonder what Easter eggs they have on Google.com, or if they have clowns employed to make fun on the site.
So, instead of searching for the job section on Google.com, search for the word “google careers” directly in the searchfield (source: Battelle)
It doesn’t work on your local language-Google however. So make sure you use the international Google.com (http://www.google.com/webhp?hl=en)
