I agree with navydad17, if possible wait to schedule BGO until right after NASS. When asked a question in an interview my son was able to say something like, “when I went to USMA I was impressed with all of the equipment they had –do you know they have a piece of equipment that cuts through titanium with a stream of water.…” He was able to talk about the "brotherhood" he witnessed.
I also agree with RAS that you should have your resume on hand. Two copies one for them and one for yourself.
All interviews asked him his intended major and branch and why.All asked about NROTC/ROTC.
All asked about plan B.
They all asked about honor code/concept and what if you were given an order you knew to be wrong.
The question that for some reason really tripped my son up was, "what books have you read about the military" He is a huge history buff and reads a lot-in fact had just finished
The Things They Carried but instead he answered, "I saw the movie Saving Private Ryan" (It could be worse, he could have said he saw the movie Private Benjamin...)
His interview with his USMA FFR and his USNA BGO were radically different. Alot of it had to do with the style of the interviewer. The USMA FFR was very polite, straight and direct. He'd ask a question, and then silently write down the answer. The USNA BGO would tell a silly "sea story" or tell the story about the time Jacques Cousteau came to speak and he was in charge of the projector and it didnt work and then the BGO would ask my son a question, then tell another sea story. Obviously my son felt better about the BGO interview.
My son also got a phone call from a regional rep who wanted to come out to the house, meet him and see if my son had any questions. My son didn't have any questions, but he said that he did have questions, figuring it was a good opportunity to get another foot in the door. This regional officer who met him was young, enthusiastic and my son really connected with him.
All in all it would have benefited my son to practice with another adult with authority who he didn't know. I suggested it, he didn't listen. worked out ok anyhow in the end.
