Saw your post. SIU said that they normally do not give interviews to all that they accept. Adcoms told me that they try to get as many as they can in, but that usually is not very many applicants. So I would not fret if you don't get an interview there.
As far as your DAT scores go from the other post, I think that they are not bad at all. Ochem is a little low, but the rest are fine. For SIU and UIC for sure. If you're 3 month waiting period from your first DAT is over, you may want to take it again to raise that ochem section. You never know, you may do better in some of the others too. Good luck.
