The “neg” Kim Jong Un approach is not a Meyers original. Earlier this month, Fortune spoke to Harrison Leggio, the founder of a cryptocurrency startup called g8keep, who said his company has been flooded with applications from North Korean citizens posing as prospective IT workers around the globe. To weed them out, he told Fortune he ends interviews by asking candidates, “Say something negative about Kim Jong Un.” Leggio claims other founders he knows are asking the same thing to thwart the infiltration attempts.
