That personal statement was way too formulated. Sounded like, and i know you did, just took blurbs off their website and put it onto paper. When you said something about the personal statement i figured it was going to be about who you are where you come from and why it makes you the best man for the job. You need to just relax man, like everyone else is saying just go in and be yourself. You seem to be trying to hard. Take a deep breath, and honestly just have fun with the interview.
