I applied in-person. The process took 3 days. I interviewed at Illinois High School Association (Barrington, IL) in Jan 2017
Interview
Had to take a test and go through a 3-day course of training. Overall was well done, it is set up for whoever wants to sign up and learn about reffing. I would recommend it to anyone who is interested. A good first job to learn about how to work.
Interview questions [1]
Question 1
Nothing was just based on the test. 100 question test about everything we learned.
