I'd say that for senior positions generally companies are looking for qualities that go beyond technical expertise (where in coding or something else). This includes communication skills, poise, etc.
That's true but the more senior the position, the truer it is. If a new grad or candidate for a junior position seems to have the skills for an internally-facing position, I'm more likely to overlook some social awkwardness or so-so communication skills than in someone more senior.
