While majoring in Computer Science at MU, not a fancy school by any means, i had a job in my field on the third year of school and by the time i graduated i had a few years of development experience. Most folks I communicated with in school had similar experience. Those who didn't were typically foreign students. Do other majors not work this way? It baffles me how someone went through their college career, at a prestigious school at that, and couldn't get some kind of job/internship.
