I don't think they do silent rejections, I think there are still interviews left to be given out. I don't know that for sure, but they seem to send out II's once per week, if that. I got my II on february 6th or something, and when I went to choose a date, there were still 6 different fridays available to choose from. and the last date was March 27th. I know it's been 2ish weeks since I scheduled mine, and I don't know how full the remaining dates were, but I would think there's still some spots to give out! I also heard creighton has a long app cycle relative to other schools.
