Nothing. Nothing is great about this.
1) Someone doesn't understand the capabilities and limitations of the state of the art in AI. That someone would believe that he can codify and embed his preferences into AI for something as complex as the operations of a company indicates a serious overestimation of what classes of problems are in range.
2) Having employees give attaboys is a surefire way to create isolated political islands and tamp down unpopular positions. It's idiotic.
3) Baking hiring into AI is, at best, penny wise pound foolish, and it could only work if the incentive structure of the company was so universally fucked that one was willing to risk employing someone over spending a few hours with them.
4) I very much want to see the inside of this shit show. I'm guessing that I'll witness a strange mix of misery and bliss. Some people thrive in douchebag-gladiator environments, and I fully expect smart people to game the living shit out of this train wreck.
Should be fun... Sort of.
