May I ask what recruit station you are heading up to, I had mine about two weeks ago up at Recruit Station Springfield, awesome guys.
Dress up nice, they will take your picture...
Just like prior stated, know your stuff, have as much completed as possible... {package}
Be up front with the guys you have to speak with, I had to be interviewed twice, I believe that is standard, so just know your stuff....
Be yourself, tell the truth...
One thing, didn't throw me but was a good question, was 'Is there anything, or anybody that would keep you from accepting this scholarship, or accepting placement into NROTC - Marine Option, any long term girlfriend, taking care of grandma, anything like that.'
So just a little heads up on that one
Also, another edit lol:
-Know what you would like to do, well you are here at Airwarriors, so that leads me to believe air

But you never know, because he will discuss the track you will take if you get it / if you don't etc.
No shame in asking questions... ask him he knows
