The only thing I was told is the categories stay the same. Like leadership, character and knowledge about usafa. There's five I believe and I don't know all of them sorry especially not word for word. I would venture to guess the questions change depending on responses so they understand who you really are. Questions about leadership may not be asked if you answer it in another question.
This happened durning my interview as I discussed teamwork, and leadership under a "have you every disagreed with someone and how did you handle it" question. I was able to explain my position in JROTC and how I change my leadership style throughout the four years.
If every question was exactly the same as another interview, the interviewers would be limited. Interviews allow candidates to show their true personality that can't be conveyed on paper. My enthusiasm and planning show led through when we discussed being track/XC captain. Something I can't write on paper to the same extent.
The ALOs are volunteers and care about the candidates. This means they'll try to offer their honest thoughts about you to usafa. The best way to do so is through the interview process.
