The #1 objection to AI interviewers is that candidates will hate them. Thats not what the data is saying though. Candidate experience scores are surprisingly strong. That’s one of the findings from my research on the category, which @SHRM just featured: shrm.org/topics-tools/news/t…

The Rise of the AI Interviewers

AI interviewers are reshaping hiring, but success depends on structured processes, governance, and candidate experience — not automation alone.

Does anybody else's macOS updates seem to nuke their local Postgres installs into some sort of black hole? I swear every time I get a MacOS update I have to re-install Postgres entirely
