My theory:

When the application forms come in, they have the interns draw either a square for paper, circle for rock, or x for scissors. Next they have to shuffle them. Now there are only a certain number they want to interview so picking two at a time they get a winning pile made.

During the interview process, they try to determine who has the essence of a rock, paper or scissors. After they come to a consensus, your name and mark is written down on a slip of paper. Now this round of janken is best out of three. Each win a person tallies when their name is matched to another drawn from the hat is marked on their slip. This round continues until they have their picks.

ps~With a shrinking economy, I would wager that you will see more cities like mine where only 3 JETs are among the total 21 ALTs.
