Work Experience In College
Most law school applications will ask you to list any part-time jobs you held while you were in college and how many hours per week you worked. If you had to (or chose to) work their way through college, this should come as good news. A great number of law schools make it clear that they take your work commitments as a college student into consideration when evaluating your undergraduate GPA.

Work Experience in Real Life
All law school applications will ask you about your work experience beyond college. They will give you three or four lines on which to list such experience. Some schools will invite you to submit a resume. If you have a very good one, you should really milk this opportunity for all it's worth. Even if you don't have a marvelous resume, these few lines on the application and your resume are the only opportunities you'll have to discuss your post-college experience meaningfully—unless you choose to discuss a professional experience in your personal statement as well.

The kind of job you've had is not as important as you might think. What interests the admissions committee is what you've made of that job and what it's made of you. Whatever your job was or is, you want to offer credible evidence of your competence.

For example, mention in your personal statement your job advancement or any increase in your responsibility. Most importantly, though, remember your overriding goal of cohesive presentation: you want to show off your professional experience within the context of your decision to attend law school. This does not mean that you need to offer a geometric proof of how your experience in the workplace has led you inexorably to a career in the law. You need only explain truthfully how this experience influenced you and how it fits nicely into your thinking about law school.
