I worked with the LT's who prepped and escorted those going to the tech and admirals interviews, there have been those that have brought up they were told to go subs via USNA/NROTC, the exact example that I was told about was the Admiral asked a mid something to the effect of "What led you to want to be in the program" the mid said he put some other designator first, was told he was going subs but that he would do whatever the USN wanted him to do. He was then rejected by the Admiral, no idea what came of him after that.
Who knows what the Admiral will ask but if he ask the question why not answer truthfully?
One of the best officers I worked with was a nuke draft (SWO-N), ended up being CO of Beachmaster unit, I hope I have that name right.
