I think you have hit the nail on the head, my interview experience at a single company (currently employed, didn't interview anywhere else) had a very high variance in terms of questions/approaches so I can see this playing a significant part in determination of appropriateness of a potential New Hire. Personal experience is important in terms of rapidly evaluating a candidate! If a team is composed of 10 people and you interview with each and each brings something a little different to the table, that seems OK to me. It gives a candidate exposure to the people they would be working with, kind of like dating.
