Hey!
I am not too sure about last year (Year 10 interviews) as I did not get an offer.
However I think they would ask you stuff like:
1) What can you do for the school? What can the school do for you?
2) Tell us one time you have displayed this value? (they give you a value such as empathy, respect etc)
3) What challenges will you face moving schools?
4) Tell us about a time when.....
these questions are similar to what the year 11 interview had.
Before you actually go in for your one-on-one interview they give u a sheet to look at the interview questions and you have time to think, its not on the spot (at least that is how it was for us).
