Weitzman: Prior experience is a poor predictor of candidate AI skills
“Sometimes people tell you that they're great at AI and then you give them the challenge and they suck. You just got a test. And sometimes people have never used AI before, and you force them to sit with it for 48 hours, and by the end of the 48 hours, they're …”
