Job Interview Questions: Job interview at McDonalds soon...?

I have an interview with McDonalds on Monday and I'm very nervous. I'm 14 and this is my first job interview:
What kind of questions will they ask?
What should I wear? I have some black pants but they aren't dress pants, or should I wear my khakis. Would it be appropriate to wear a polo or a dress shirt with a sweater vest (I don't have any ties that match my shirts) And should I wear black dress shoes or just tennis shoes?
And Finally when do they tell you if you got the job?
Before you say something about my age, I can work at 14 in my state, why else would they call me in for an interview, my age was on the application

Job Interviews - Do You Really Want the Job?

Recommended Answer:
I worked at a Burger King when I was that exact age. My employer told me to go home (one hour away) and change into some dress pants (true story). Wear dress shoes and anything that looks professional. Wear your "church" clothes. With the interview, they're going to ask you about your employment history, why you want a job at McDonalds, and then eventually they'll tell you that you have to show up on time for your shift, you can't be late, you're supposed to keep nodding your head, and ultimately they'll give you a job.
