If you truly are this nervous about a little interview I would seriously advise you to consider another career. Its a very stressful job and surgeons and anesthesiologists put you "on the spot" quite a bit. I'm saying this so you can think about it before you spend thousands of dollars to work a job that may make you miserable in the end. Being at the head of the bed is not a fun place if you are a nervous person. Seriously.
