They called "assessment day". Period: 9:00 to approx 13:00. First of all, candidates start with an brief introduction to others. Then, each candidate will do presentation one by one with length no longer than 5 mins. On my assessment day, topics were: my favorite project, the life in the future. After that, assessors (5 in total on my day) will ask you questions related to your project. Then, you will meet with other candidates and spend time on team activities (board games mostly on my day). At the meantime, morning tea will be provided and you will have time visiting this company. Eventually, you will be invited to have an 1-5 interview with assessors (around 4-7 mins).
