Yes working hard and competent is the bulk of it. But we've met people like that we simply wouldn't bond with. Culture fit is hugely important, and if you hire a cultural misfit, it's much more difficult to fire them.
Since the concept of "culture" is so vague and no one using it seems to be able to describe what exact set of criteria it represents, it appears to be whatever a hiring manager wants it to be. If you don't like someone's skin color, religion, cultural background, the fact that they don't like drinking or going to team-building trips every weekend, or you just don't like the color of their shirt, it's easy to reject them on the grounds of not being a "culture fit". Who cares about their professional skillset when you're obviously looking for a paid buddy.
