Hey freddyfreddy 🙂
The Walsh Interview was more of a marathon than a sprint. Expect to stay for 2-3 hours. There is a group interview and a group activity (which you probably already know from the itinerary they sent out). You will eat lunch with faculty and current students (the lunch part is not very formal, more of a pull up a seat and get to know everyone, which I liked) Current students will show you around the facility. The students and faculty are very nice and made the atmosphere comfortable. In some interviews it seems like the interviewer wants to make you nervous and see if you will slip up but that was def. not the case at Walsh. The specific kinds of questions they ask are more of the "name a time when..." "how would you/did you deal with..." type questions and because it is a group interview you will have the opportunity to think out answers while others respond which I found beneficial. The actual interview is not very long (only 15 min) but it seemed like plenty of time and they also allow you to ask any questions to the faculty that is interviewing you.
Hope this helped and Good Luck!
