I understand some information needed. This thread is about going too far and what they will want next.
Then I, as an employer, would file you under "Not a Team Player" and hire someone else who didn't give me such a hard time. :-) One of the previous posters nailed it - this *crud* is mostly just to give the HR wonks something to do and an opportunity to feel important. Do you really think that if you interview with a manager, and the manager wants to hire you, that HR will step in and say "No can do! Freepinglurker scored an XXXX on his personality test"? And honestly, I wouldn't want to work in company where HR had that kind of clout.
Having just changed jobs recently, I've played the interview game with a number of companies. No personality tests, though.
I've got to say that I take a fairly aggressive tact - I'm really interviewing them, and not the other way around, which to me honestly is the way it works. In a job market as good as this, the question that needs to be asked is not "Will you please hire me?", its "Do I want to work here?".
My lack of deference worked, I guess. I had my pick of 3 offers, including the place that I really wanted to work.
