If you're a freshman in the true sense of the word, meaning 18 years-old, I wouldn't worry so much about the job market in your given career. I would worry about getting the best grades you can and staying off of Facebook. Meaning don't post anything you don't want your future employer to find in a background search. No beer drinking, no naked pics, no stories of drugs. No stupid sh%t you wouldn't tell them about. Facebook and every other social networking site will be looked at by every company doing a background search. Any, and everything you post is fair game.
I would try to get a part-time job. Even serving coffee. Internships, volunteer, etc. Anything to show an employeer that you are willing to be a team-player and you work well with other people and are willing to do crap as well as your given *career*.
If your career is engineering, you have a much better chance of getting a job than if it is in, oh, say Art Appreciation.
College can and should be fun. However, if it is too much fun, you'll be there for 5 years which not only adds to the cost but puts your career on hold. Plus, you are there to learn not party. (speaking from experience. )
