Might just be me, but I only had to submit one application when I was 16 :gotme:
Anyways, when you submit an application, make sure you follow up on it. Don’t wait for anything to be handed to you, because you’ll be disappointed if you do. Also, if you get an interview, it is never a bad idea to write a thank you letter, and make sure you dress respectably/presentable. If your not sure what to wear, it never hurts to always dress up instead of down (should be common sense).
