What is means is that now hiring is symmetrically broken.

Hiring has always been broken. May be not completely at the FAANG level, but below that, and more importantly across the globe it's seriously broken, and there's a high variance when it comes to hiring consultants quality.

The widespread use of AI vy applicants is very likely surfacing how comfortable consultants were doing the bare minimum when hiring.

I know for a fact how crappy work around hiring is.

P.S.: the article focuses mostly on one direction of hiring. The opposite direction is also suffering from this (briefly explained in the article about AI fueled hiring bias). In my opinion, that is an even greater problem.
