My best advice to you is to be confident. Despite nervousness, if you come across as confident in your responses, they may look at you as more responsible (and not just some kid living with his parents).

Mal is right, don't settle for a very low wage. nwlinkvxd (my fiance) started doing programming, IT, and all kinds of computer jobs for a company that only paid him 10$ an hour. Come to find out a few months later, people that do the same job as him (or maybe even less) are making an average of 28$ an hour. nwlinkvxd was lucky that he was able to negotiate for a wage up to 26$.

Also, make sure you have enough for living costs. For example, yes, the minimum wage for the nation is 5.15$ but in many states, state minimum wage is higher because of costs of living. Make sure you're getting paid for the living costs inflation, and then some.

Flaunt your experiences, even if you don't have any in the field you're going into. Since they know you just graduated, flaunt your grades, the clubs you participated in, past jobs while going to school. If you make them believe you're a good employee that will put out quantity as much as your salary that they're paying you, you can get the job.
