I just interviewed at my top choice school this past monday. I don't think the interview went particularly well) so I am freaking out because this is exactly where I want to be for the next four years. Would it be wise to send them a letter of intent telling them that if accepted I would DEFINITELY go there, even though I already interviewed? I have spent a lot of time at the school over the summer and for various other reasons so I have a valid reason that I'd like to go there. I'm just wondering though if LOI's only work if you have not been granted an interview yet? Any thoughts? Thanks!
