I added my paid clinical experience for my work experience. I think it serves three purposes: 1) if you have a gap between undergrad and medical school they would want to know what your line of work was, ie, career change, experience, etc. 2) if you had a meaningful medical job. I was a PT => FT pediatric medical assistant during my victory lap in college so I put it in my app. Figured it can only help, surely it won't hurt. 3) if you worked in medical school.
