First, If the college requires or offers interviews, look on the college's website or contact its admission office to find out what you have to do to set one up. If you have to travel to the college to interview, you may want to schedule a campus tour for the same trip.
After you've scheduled an interview, you can do several things to prepare. One important step is to research the college so you feel ready to talk about why the college is a good fit for you. You can practice interviews with family members and friends.
