I submitted an online application, and was then invited for a phone interview which lasted for half an hour. I was asked questions such as
1. Why Macquarie
2. What do you enjoy doing outside of school and how do you balance your time between co-curriculars and academic work
3. Why Risk?
I was then invited to a psychometric assessment which was 2.5 hr long and included numerical, verbal, logical and personality tests. I did not pass this stage.
