alt Hacker NewsJust speculating (I use zero automation when recruiting), but automated candidate ranking systems could well still look for signals that were valuable years ago, but no longer are. It's not a given that people using this stuff even understand the criteria under the hood.
Same story as SEO, I presume. Google surely understood their ranking criteria deeply, yet couldn't exactly win that fight.
Google could have easily won that fight by blacklisting scrapping spam sites and spam portals. They just didn't.
There weren't that many with high ranking. I could filter out most of them in like a week of working normally and just right clicking them with the blacklist extension in Firefox.
Nowadays it is probably harder though when Google have broken the internet culture.
