Found the job listing through an online job board and applied - online applications only required work history and some details relevant to the role.
Received an invitation for an interview 1 week after applying, with multiple times available for a group interview. Interview had ~25 people, and there were 3 activities that we had to do. Mainly trying to gauge how you would interact with others and find out a bit about your personality.
1. Play a game in a 'drama' game as a big group, which involved going around a circle and reacting to 3 commands. If you made a mistake with the command, you were 'out' and had to sit down.
2. Partnered up with someone else within the group and had to learn a few things about them. Afterwards, asked to introduce this person to the group and tell them about the things you learnt.
3. Split into groups of ~5, and were asked to write a song about Dreamworld - basically rewrite the words to a previous song, then get up and present it as a group. Encouraged to really get into it and get creative about it.
After, a bit of paperwork (availability, etc.) and some basic competency questions (spelling, maths, etc.) and then we were free to go.
