Hey, they will ask you some basic questions. Here is an article about that with some advice: http://www.workopolis.com/content/advice/article/ten-questions-you-are-sure-to-be-asked-in-every-job-interview-and-how-to-answer-them/
Regarding questions you can ask, try something about the company or the specific operation. I assume curry's is some kind of restaurant franchise? Well if it is, then you could ask how for example restaurant staff use the computers, so what for, etc. Just stuff that is not quite your job, but still kinda relevant. You can also ask questions about the job itself; if you read the description and think of any, you could ask that. The goal is to appear curious and engaged.
It's really great that you are doing all this at your age. Very thorough. Good going! :)
Dependability.
Would having served on my college's student government senate and finance committee be enough? I'm also part of two honor societies and honors program. I'm just trying to give you information and I hope I don't bore you with this.
Flexibility.
I am thinking of showing my spring semester schedule and make them see I am more inclined to work weekends because that is when I am free. Would that lower my potential as a employee to the employer or would that have no effect? What exactly would I say that would make me stand out as flexible, even though I might not be so.
I am definitely eager to learn anything they throw at me. I try to read up on books related to business in my spare time. Although I am not that fast I have made some progress in "How to make friends and influence people" by Dale Carnegie and "The Intelligent Investor" by Benjamin Graham. I am willing to give my 100% because this will help me get my foot in the door while providing me will invaluable experience!
