Edwin Guarin, "EdVangelist," has been in your shoes as a student. He has also been the "paratrooper" of enterprise business support... on call at any moment to jump on a plane, go onsite to customer locations, fix mission critical issues, and maybe grab a sandwich on his way home. Now, he's in front of students like you every day discussing where industry is going, technology today and how it can help you, and ways for you to learn and find your passion.
Edwin gave one of his famous interactive talks to students at the Imagine Cup 2008 US Finals where he discussed the future of the job market and ways for students to prepare. Check it out and get some advice from the pro.
