I'll give you some advice for free, whenever you go for a job interview carry at least 5 copies of your CV. That should be enough for each member on the panel. It gives the interview panel the impression that you actually thought about what would happen in the interview and that you planned ahead. It also gives people the chance to browse through your history, and learn more about you when one of their colleagues is asking you a question.
It doesn't matter if you are straight out of high school. You must have volunteered in some organisation or participated in some kind of extra-curricular activity at one point in your life. You always learn new things and grow from these experiences so don't be afraid to mention them. They could go a long way in helping people understand what kind of a person you are...
all the best people.
