This is an interesting question, since the two extremes of possible answers may be "correct" depending on the role you're trying to fill. If you're looking to fill a strategy- or project-related role, where the candidate will be bouncing from project to project on a weekly or monthly basis, you want someone who is easily bored and constantly looking for new challenges. If you need a competent manager or staff member to run a steady-state process and sweat the details, you obviously want a very different candidate.
