I am assuming that as a young "military brat" one of your parents has arranged this "interview" for you and that you have in fact "done your "homework". Also, I am assuming that you are considering a career in SF. If these assumptions are correct then a {salute} to you for using your head and gaining some ground truth SA before making a choice. BTW I have often said that if I were 20 years younger I would have had made SF my career choice.
So to answer your question: I would recommend that you ask two very broad types of questions: (1) From their perspective, what do they see as the future role for SF given the nature of the changing geopolitical climate and the assumption that asymmetric warfare will be the nature of future conflicts? (2) What do they consider to be the most important personal attributes for a prospective SF candidate? (3) Since SF now has branch status in the Army, compare the officer and NCO career paths. What could you expect as an SF Officer or an SF NCO throughout your career?
Take good notes during your "interview" and I would suggest that you post the Q&A here to get some additional feedback and advice.
Good luck
