Is it just me or does it seem the people who have passed the personality tests say that they are useful, and the people who failed saying they aren't useful. I apparently got a high score, so I suppose I should be happy.
People who know more about psychology, such as Steffi and the people who set the tests say they are very successful. Although I suppose they will always say that, as it gives them more work.
I imagine that they probably could help determine who would be useful at a job, although Im not sure people should fail on them until they are interviewed by a professional HR person and go through it again, as then factors like body languague could come into play to help get more accurate results.
