Interviews run after school on Thursday, August 20, starting at 3:00. You will sit down with a panel — industry professionals and school administrators asking you questions together, rather than one person across a desk. That sounds more intimidating than it is. They are not trying to trip you up; they are trying to find out who you are.
Part one: your speech. Up to five minutes, prepared ahead of time. Two or three minutes is plenty — five is a ceiling, not a target, and nobody has ever been marked down for finishing early. Cover who you are, why you want this office, and what you would do with it.
Part two: questions. The panel asks you a round of questions and you answer them. There is no trick question. "I don't know, but here's how I'd find out" is a genuinely good answer.
The whole thing is short. Wear Official Dress if you have it; if you don't have a jacket yet, dress nicely and that is completely fine — it is not part of the scoring.
What actually helps: practice your speech out loud at least twice, to a person, not a mirror. That is the entire preparation secret.
