I am curious as to what the final doctor interview like? Are they recapping everything you just went over and talked about?
Uneventful. The head doc may not even make eye contact with you while he/she asks you simple questions like have you ever had any surgeries, broken bones or are you allergic to anything etc. This is not the time to try to recall a bad reaction to a bee sting you had when you were 12 years old. The doc is basically just looking through your packet to see if any "no go" boxes were checked off. If everything is okay you'll be in there for five minutes tops and be sent on your way.
If it makes you feel better, when I woke up @ 4 am to do MEPs for the day I threw up because I was THAT nervous because a lot was riding on my passing that day Just ask away any questions and look up on the forums, a lot about MEPs on the board.
