Hi, yes the interview day is pretty long. I think like 8am to 4pm maybe. Bring a snack if you need it. The lunch break is about an hour. You will need to drive to lunch, so if you don't have a car then carpool with another interviewee. Up the street there is Taco Bell, Subway, and Arby's. Behind Taco Bell there is a burger place called HUDs that is good, but it might take a little longer to get your food. Those places are the closest. If you go a little further down Coulter there is a McDonalds, Wataburger and Taco Villa.
Tips for the interview...the student interviewers should be really nice, and get to know the other interviewees because you will probably see them next year. The day is long so try to have fun and relax. When driving to school in the morning on the snowy/icy road drive slow. Don't let other people make you drive faster. Also, when getting into the turning lane going into parking lot slow down slowly so you don't slide or anything. The road should be fine, but just incase.
Good luck and enjoy the snow!
