Interviews

Hello, I wanted to ask a few questions about the interviews (if I make it). I'm applying to AAST if that helps in any way.

1) How many questions were asked? I just want the numbers and I know it changes from person to person, but I want a specific number from the people who experienced it.

2) Do they ask generic questions like why did you choose this academy, or are they more specific, or a mix of both?

3) The attire is supposed to be business casual, I'm still confused about that even after searching it up. What should a girl wear to fit this dress code (like a blouse or something?), or if this is easier to answer, what should I not wear.

4) I heard they ask a lot about what you put on your application essays. Is that true? If so, should I basically memorize what I wrote.

5) Finally, does anyone have some sort of idea or theory of how they choose the people from the interviews?

Anyways, thanks in advance to the people who answer this and hopefully I make it to the interviews otherwise this post would've been a bust for me.
