I got offered an interview at Sydney Tech a week back. They asked some of the most unexpected questions, such as 'What do you do at a daily/weekly basis?' That question took me completely off guard, but somehow I managed to sneak out of it. Be prepared to say your subjects for next year again, as well as having a good sleep and breakfast.
Some questions that were asked at STHS and may apply to your school:
- What do you do at a weekly basis?
- Why Sydney Tech?
- What can you do for STHS?
- If a teacher were to write a reference, what would he/she write about?
- Did you take the selective test in Year 6?
- Possibly something regarding your subject selection (Note that I didn't choose any science subjects for STHS lol bad move?)
- Make sure you ask questions about the school (Pretty much anything, even if you don't really care) because that shows you have an interest at this school, as well as some sort of curiosity.
- MAKE SURE YOU KEEP EYE CONTACT ON THE TEACHER(S) AT ALL TIMES. Shows that you are confident in front of them.
Hope that helped, and good luck!
