I interviewed with them last year and it was definitely not hard. I got accepted but rejected the offer and went to a different school. But, based on my experience interview day was very laid back and I felt very welcomed. I don't know if they are changing things this year, but when I interviewed it was by a faculty member and a PY2 student in a small room. I can't say too much about it but I was more nervous before the interview than during the interview - it was more like a conversation and like I said, very laid back. One thing I noticed that WSU emphasizes based on their website (before I did my interview with them) is inter-professional education, which is working with other healthcare professionals. That reminds me, make sure to study their website and what their programs offer.
Like I said, this was last year and a lot may have changed, but, as obvious as it may sound make sure to study for the interview - practice makes perfect. Keep in mind also that if you got the interview invitation then you are almost there; you got through the hardest part and all you need to do is for you to get to know the school and vice versa. Also please dress up. It made me cringe when I saw a guy where converse with his suit. Best of luck to you all
