I'm confused by your patronizing tone. You seem to think I don't know that this is common practice.
See, the point of the prior post was: I disagree with this premise. The question should be, "How well does this person do the job" not "how well does this person match my preconceptions about how an expert in this job should look." This is especially the case in the world of software and software products, where we're notoriously bad at identifying talent and educating people.
Anyone who's designed tech interviews with a high technical standard can tell you that years worked is at best a weak signal.
