Work permit for Baltimore minor?

I'm a little confused about how a work permit works. I've been on google all morning and i'm not really getting a straight answer. Yesterday I turned in a application to work at Rue 21 in Dundalk. The man at the counter said when he calls me I have to have a work permit. I looked up templates and online application sites for them but they all say to fill in the company name. I don't have a job yet and i've never had a job either. So am I supposed to fill out the work permit for that specific application or do I fill it out after I receive notification of being hired? I'm ridiculously confused, please help.
