Allright, Piccard, I'll try again (though with less enthusiasm):

ALL job interviews, for ANY job, are, in essence, a psychological exam. They want to see how you respond to questions (even odd-ball questions), problems, and scenarios. They want to hear how well you speak and articulate your thoughts. They want to hear your first, gut reactions, to questions in attempt to judge your character, moral clarity, deciseveness(sp?), etc.

I've been through "oral board" interviews for hiring and job promotions, and have been an oral hiring board panel member. Scenarios can be created where there isn;t really a right or wrong answer, but rather it's a test to see and hear what you do. Adaptability, judgement, adherence to law and policy, moral clarity, imagination, and a host of other criterion are trying to be elicited during these interviews. Many times, no matter how the interviewee answers a question or responds to a situation, the panel will change the scenario....build on it.... just to see what the interviewee does.

It's not an exact science.... it's just a feeling-out process. They want to see, hear, and try to understand who they're getting (or not getting).
