Interview Tomorrow Hell Yeah
Look in a mirror before you walk in. You don't want a grease smudge or food on your face, lol!
Study anything tonight that you might need to brush up on and bring a pen with you as well as notes. I always bring everything with me in a large daytimer or attache. They'll probably want all kinds of info like names and addresses of 3 business references and possibly 3 personal references.
Be confident and ready and look your best. :)
Good luck!
