The UMSL interview is really laid back. You show up at about 10am and have a quick meeting with the student advisor to make sure everything in your file is correct and to answer any questions. They walk you through an overview/presentation of the program and school. She also gives you answers to some of the interview questions. A couple students will take you on a tour and treat you to lunch. Then they call you in one by one for your interview. I had two faculty interview me for ~20-25 minutes. Check out the interview link under "databases" for a list of questions they ask. After your interview, you head home and wait by the computer for them to email you. They sent me an email at midnight saying I was accepted. It was that easy. Good luck!
