I've been part of a three-person panel for interviews at multiple companies. I think the idea of panels is first, to train people to be good interviewers. Second, to get the opinion of multiple people regarding the viability of candidate. Third, I bet there's a liability thing at a company level where they don't want a candidate who fails to be able to claim bias of one person.
