Hi there, after just coming out of a video interview today (same as you with the 6-7 hour travel time) I can confirm that it took around a week for the university to schedule a new interview for me which was far later.

Hope I was able to help, and I hope that you get in to the university, it's my first choice too! (Taking a degree in Graphic Design)
