They use specific stats to determine it, you don’t need to show them anything. If you want to join, try playing a lot and being professional with your grammar. It also might help to join other departments via applications (in the discord server under staff → announcements, usually every few weeks or months some department will open them) if you can handle the additional work. So you don’t need to speak with anyone until maybe you get a DM saying that you have been handpicked.
