Make sure you have a good answer for this. Give a lot of detail about you and you're experience without going to deep and getting caught up on 1 topic. The beginning of mine went something like this... I was born and raised in Dayton ohio I started a family at a young age and I think that's what gave me the drive I needed to be successful. I actually worked 40+ hours while I was still in high school in order to provide for my family. After graduating in time I realized I needed to grow up quick and the best place to do that was the Marine Corps... Then I go in to briefly describe my boot camp experience, how I specialized as a Military Police Officer, then why I went to college after my enlistment, and why I chose the college I did. Simply put, stay on the surface. Cover all of the important stuff without diving too deep into anything or this could quick intro could last way too long.
