Unless it's investigative in nature, even the best interviewers still don't take the spotlight.

Larry King, on his interview technique, said "The key of interviewing is listening. I hate interviewers who come with a long list of prepared questions, because they're going to depend on going from the fourth question to the fifth question without listening to the answer"

Though I can't say I blame the interviewer. If I spent that much time flipping through a thesaurus crafting my questions, I wouldn't want to divert from them either.
