While I agree, it would be irresponsible to exhaustively interview isn't a key metric for a _good_ hiring process how efficiently you can find/place candidates who _do_ excel in the role?

By that turn, shouldn't a responsible hiring manager constantly be evaluating and improving their heuristics so that their front-line filtering is less biased and stupid in the ways that materially affect the quality of hires?

I don't think the point is that we can remove heuristic filtering from the process. Heuristics are necessary in hiring but this doesn't justify being dismissive of a discussion about whether a certain class of heuristics is really serving the needs of the organization.
