How did you know you were "on hold"? Did they tell you over the phone?
FYI, I asked Wake Forest if I'd be granted an interview because I'll be travelling near there. And they wrote back, "You are in the interviewable pool, not the pool we are interviewing at this point in time"... I guess this means I'm in the "maybe" pool, vs. the applicants who are in the "hot applicants" pool
