Eh - none of my good jobs had this style of interviewing. I'm not sure I'm missing out on anything.
I am gauging the interviewer from a human perspective, and you're exhibiting behavior that I cannot respect. In general, I advise people not to work in teams if they don't respect their coworkers, and never if they don't respect their manager.
I like discussing these topics in interviews, as long as it's not a one way discussion. For the last job I interviewed, I got loads of interrogation style behavioral questions from all the interviewers (you can likely guess which company). Yet none of my interviewers could answer a simple question adequately:
"What are the reasons people leave the team/company?"
Very tempted to have acted like you did when they gave lame answers.
Edit: I think my comment doesn't convey my thoughts well, so I'll give another stab at it.
In general, if you want people to be open with you, there needs to be some kind of reciprocity. Playing psychological games causes people to raise their guards, and the natural response is not to give you what you want or be evasive. In an interview setting, that doesn't look good - so the next natural response is deception. Your style of questioning (I'm guessing here as you didn't give details) does a good job of eliciting the behavior you are trying to weed out. And then as a result, you get confirmation because you think you've caught out a guy trying to deceive you. Yet your behavior is likely a serious contributing factor.
