There you will find all the help you need. Otherwise, my SIU interview consisted of a 100 word paragraph on a situation they give you. Then, you meet up with your interviewers - one professor and one student- who have a general conversation with you. Oddly, it was one of my more awkward interviews cuz the interviewer paused a lot and would wait for like a minute after i finished talking... maybe he wanted me to say everything I wanted to say.
next, my UIC interview consisted of a quick group meeting/introduction. Then we were sent off on two 20 minute interview rotations. Finally, we talked to D3/4s, got a school tour and were sent home. I was fairly comfortable with my UIC interview - my first one consisted of a bunch of ?s they threw at us. My second consisted of a casual conversation.
Good luck with your interviews.
