Good advice from Charlie O'Donnell over at Path 101: 10 Things Every New College Graduate Should Do to Find a Job
The one thing I would add is that you shouldn't wait until the end of your senior year to start doing the things he suggests. You should start doing this towards the end of each year of college, so that you can get summer internships as well. Whether summer internships turn into full-time employment after school or not, they can be a fantastic way to learn what you like and don't like about different types of jobs.
I worked at HotJobs in the summers of '99 and '00 before joining full time in the fall of 2001. Those small summer tastes of internet startup whetted my appetite - and here I am nine years later, proudly looking back on four and a half years of startup success at TheLadders.com.
So, new college grads - and college students of all ages - take heed of Charlie's advice.
