SIU doesnt require interviews for acceptance; they are one of the few schools that do not require the interview. It is not even considered an interview, it is just a tour/visit day. Occasionally they ask to meet with a student if they are an iffy applicant to determine their quality. It is very informal and enjoyable. I work in a SIU-SDM lab, and there have been hardly any applicants tour/visit this year that I have seen. Alton is a rough town even though it seems nice based on the school alone. Make sure you look around all of Alton (especially downtown, Broadway and Washington Streets) to get a real feel of what it is like to live here. You definitely want to sleep with the light on in Alton.
