Just because you exceed the minimums to work here doesn't mean they are going to ask you to interview! I think on average most new hires who come here have between 1500 to 2000 hours and a four year degree, unless you come from UND then they will take you with less time.
All I can say is try again they really like it when people really want to work here. I f you don't mind me asking why do you want to work at Horizon?
