When they are finished, be sure to ask if you can chew gum at work LOL
Usually the person or persons that are interviewing you will be asking the questions. The only thing you might ask about are if there are any medical benefits that come with the job and maybe how many hours you might be working. But if I were you, I wouldn't ask anything until they are done asking all about you and what you wish to do at work. Let them ask the questions.
