How much will the interview impact my application?
I think that I did pretty bad because I am international student and my speaking sucks.
Will it hurt my application?I was really nervous and forgot to say things I planned to say 
I really want to study at NYU
Which program are you applying to at NYU? It’s a huge university, with many international students, and so I’m sure they take that into account. Some programs, such as the Film and Theater schools, will place more importance on in-person interviews than others.
