It's interesting to speculate about how 'cultural fit' supplanted 'doing your job'. By its nature, a so-called strongly defined culture is exclusionary, and has more than a few Orwellian undertones. On the one hand, there are rules of HR. That's fine of course. Social guardrails for the workplace. On the other hand, there are true individuals and eccentrics. Even HBR has tolled the death knell for 'culture fit'.
