In the instances I encountered, 'culture fit' was the phrase we used to describe it. Communication style counts. Does the person have a sense of humor? I'm not talking about enduring off-color jokes or remarks, but are they going to be on the same page as the rest of the team about when it's ok to be a goof, and when it's better to just shut up and get work done? How does this person react to a crisis? Different teams have different tolerances.
