This reminds me of a personality test I took to work at a chain resturaunt called TGI Friday's.
A lot of people said it was a lie detector test but really it checks how consistant you are with your personal and professional life. I managed to get a 30 out of 50 because telling the difference whether or not they are asking what you would do in your personal life or during work was not clear.
So a question like:
If your car broke down would you call a mechanic first or a friend?
Then they ask the same question but word it different:
During a lunch rush you're over come with work do you ask for help or handle it on your own?
There really isn't any failing these tests it just determines your ability to answer consistantly.
And yes I did get the job.
