I know this is probably the typical answer, but just be yourself. Nova has one of, if not the most, laid back interviews you will attend. They are really just trying to get to know you. Let them know about yourself and use the day to figure out if Nova is right for you. They are not going to ask you any difficult questions or try to stump you. I only was asked questions about my application, but spent the majority of the time talking about Boise State football. Hope that helps, if you have any more questions feel free to PM me.
