Personnel Departments shouldn't even the last step. They should be ones welcoming you aboard on your first day.

Disagree; there is such a thing as behavioral / fit, and I'd rather have someone neutral in there (not just the hiring manager), and that person should be staffed out of HR.

Seems to me the fit that matters is within your innermost team members. If you can't trust your teams to hire for themselves, you have other issues.

That's not how you build organizational culture, that's how you build fiefdoms of toxicity and exclusion.

Fit is way bigger than two pizzas.
