This implies that culture fit is a guise for discrimination. Which, let's be honest, is what it is in most cases.
An old person doesn't fit the culture of a young tech startup. A woman doesn't fit the culture of the executive level. A black person doesn't fit the culture of the new neighborhood. A guy that works out every day doesn't fit the culture of a disruptive and innovative company.
Whoa there, culture fit may be a guise for discrimination, but I don't think it's in the same sense you're referring to. Rather I believe it's along the lines of, 'we don't think you'll drink the kool-aid like the rest of us do', and regardless, just because someone is qualified for the job doesn't mean they're the right fit for it.
