Some people may laugh at this, but there is truth to this.
During my college years, I worked for both Disney and Universal (in California). My interview for Universal was actually an audition, and we didn’t even find this out until the way end. There were multiple Universal representatives in the room, but they didn’t tell us who they were. They put us in groups and gave us various tasks to complete and we had to present each task. Long story short, the audition was a test to see who had the most natural energy, “pizazz,” and personality. The representatives were actually managers from different park departments and were taking notes on our behavior. The ones with the most energy were offered to work in operations (attractions). The ones who were a little less energetic and fun were offered sales/food, then the next level was shows, I think, and the last was character handlers. The ones who had no energy or character about them at all were told thanks for coming, but no, and we’re not offered a job.
As someone who’s worked at DL and USH, I would say working at theme parks absolutely takes skill, sometimes multiple skills.
