Some of you people are talking out of your a$$es.
You don't know a thing about personality tests.
There are some very good ones out there. And they can make great predictors as to whether or not a candidate will be successful in a particular job in a particular company.
You don't FAIL these tests. They look at your results and compare them to the results of successful employees in the company.
Some of you may have had the 'pleasure' of working for a company where you, your personal style, your working style just didn't fit the culture. It's not a failure, and it doens't mean that there's anything wrong with you. You just don't fit.
That it was the selection process should be about. Finding out if you and the company are a match.
Sounds like mindless psycho babble for sheeple, if you ask me.
Do they allow the person taking the tests view these results?
