I think the interesting addition is his point that adding some amount of literal randomness to stages of the process would be a good thing, if the culture around interviewing could change to accept it
I think he's specifically alluding to doing something like Bayesian exploration/exploitation -- which would be very interesting. Unfortunately, you'd need to hire at huge scale to assess the outcome of the experiment, and - as he mentions - it would be hard to get hiring departments to accept.
