Hey, sorry this response is coming a little late. I just interviewed there last Friday. I think their last interview days were yesterday (monday). Anyway, I was in the same boat--sent in my secondary around October and didn't hear anything from them. I finally started calling the admissions office about every week to find out what was going on. The secretary couldn't tell me anything, so I then started asking for an admissions counselor--same thing: wait another two weeks, you're on the waitlist to get an interview. Finally, last week, I called and told them I really wanted to interview there before their interviews ended and that I would be willing to drive there the day before to be able to interview. He said he'd call me right back. He called me about 5 minutes later and said there was one slot available on Friday. So, I drove down there the night before and interviewed. It was a little frustrating to wait for so many months to finally be able to interview there. They told us there were about 30 seats available among about 100 interviews.
I'm not sure if they'll interview again this year; it would definately be worth your time to call them and find out.
