The interview is simply a way for them to learn more about you, your goals, interests, etc. As far as being better or not, it depends on how you look at it.
Many kids have enough interaction through AIM or other events that they feel they know them well enough that they don’t need an interview.
If you do get picked for an interview, at the very least they’re interested enough to talk to you more, so there’s that.
If selected, you have no choice but to do it if you want a chance of an appointment, so it’s a time to shine and tell your story. Conversely, it may not go great depending on your level of preparation.
That being said, I know enough folks who are admissions partners who conduct many of these interviews to know it’s not their goal to try to “get you” and make you sweat. They want to learn about you as an individual, your “why”, and how you can contribute to the academy and the service.
Don’t waste any energy worrying about that. It is what it is. Just take it as it comes and put your best foot forward!
There are no silly questions. For the most part.
