I second that (interviews are just another data point) from my CBS experience.. when I talked to my interviewer after my ding, she was nice and honest to me that she had given me a strong recommendation for admission, and high marks on all points, and wasn't sure why I was denied adm.
I wish they had made up their mind. before the interview ..so I could've focussed more on my Ross app. ....
oh well, interviews are always good learning experiences.
