1. You just have one 45 minute interview with two faculty members at the same time. Sorry if I didn't specify that. All closed file.
2. They had a list of questions they HAD to get through. Before you go into the interview part of the day, they sit you all down and tell you exactly what you are going to be faced with in the interview room. The interviewers are allowed to cut you off because they HAVE to get through all the questions (for example, I didn't have a good story/answer for one of the questions so they just kept rephrasing it and then since I still couldn't come up with a specific story (as opposed to a general answer) they made up a situation and asked what I would do.) They also told us that each interviewee has the exact same questions. But yeah after you give your initial answer they will ask more questions on that topic being like "And how did that make ___ feel?" or "Did that change the way ___ acted in the future?" etc etc.
3. There were ONLY situational based questions. Except for "Do you have any questions for us?"
Yes! There were other activites throughout the day. I was there for about 5 hours. We had breakfast, an orientation, interview, tour, financial aid presentation, research presentation, and finished with lunch with two D4s.
Besides the actual 45 minute interview, I found the day to be really enjoyable. I don't think I knocked it out of the park (as seen above, I struggled with a few questions), but I think I kept it together enough and gave a good enough overall view of myself to not be completely stressed out. It was definitely a difficult 45 minutes, but I left feeling relieved.
Best of luck.
