Ugh, sorry to hear that, I hope Duke comes through for you. If you don't mind my asking, what makes you say that you could have been more enthusiastic about Stern? What did you say (or not say) that makes you feel that way?
He asked me "What do I look for in a school"
I replied with "tight knit community with an international focus", and I explained that I like the social aspects of the school, and that the students were, in my experience, more extroverted and outgoing than students from other schools (notably Haas). Also, I explained that the school had a surprisingly "tight-knit" feel to it, even though the school was in Manhattan. I also explained to him that a very diverse international student body was important to me, and that I was excited about Stern's DBi programs.
However, when I look back on it, I guess "tight knit with an international focus" could apply to pretty much any B-school.
I don't mean to pile on but it sounds like your answer could be applicable to other schools in NYC. That might have raised a red flag but you never know. The application process is a black box.
How I answered this question was to list classes/professors/programs that are specific to NYU that I would want to do and how they blend into my goals and who I am as a person. Maybe this is helpful for your other interviews.
