I go to the University of Waterloo in Canada and as a second-year (sophomore) have already worked at a startup for an internship. I got that internship because of the co-op program at my school --- startups often hire from it. I'm not alone, either: several of my friends at UW are or have been startup interns. One friend is interning right now at a YC startup.
That's not even to mention the huge hackathon movement that has swept technical schools across North America. Startups have a huge presence in hackathons at UMich, Yale, MIT, UPenn, UW, University of Toronto, McGill University, and many others.
