Hm.. Well I don't have experience from Sydney Boys but I just had my interview at Sydney Tech today.... Usually interviews ask about you (well obviously). They ask about why you have chosen the school, how you can contribute, how you contribute in your current school, what you do outside of...

Lol it was like... Ok first 10 questions... easy.... next 10 ok.... next 5 was wow? and the last 5 was just guessing marathon because our time was cut :(, but I think the last question was like 250-something
