Keep it to one page that is the length you will be using when applying for attorney jobs out of law school unless you have some crazy experience. I doubt the admissions committee will spend more than 10 seconds looking at your resume unless you have something crazy on there i.e. NFL football player, Navy Seal, Journalist for the Wall Street Journal, or something along those lines. If it is 2 years at company X etc, etc then it really won't hurt or help your application and the majority of the committees decision will be based on numbers as it almost always is.
