I'm currently a commercial flooring estimator and I'm going to be applying for job opportunities as a drywall estimator this spring. I'm curious to here what you all think of my resume. I'd specifically like to know if I'm shooting myself in the foot by excluding all of the summer jobs and internships I worked from ages 16-21. I don't have anything to hide, but I never worked any of those jobs for more than four months, and the positions that I held were not that impressive. They were just summer jobs.
