hautney and hoopdreams-
Psych tests are rarely used as a sole means of hiring. If they were, yes they would have gaping loop holes. Interviews are essential, but can also be manipulated. Think of the process as layered. One has to show consistency throughout, those who manipulate either test will be eliminated because of their inconsistant profile. As for tests being developed to find ways of eliminating candidates, well where I work that is rubbish. You can be very weak in many areas without being eliminated. Candidates are 'profiled' if you will, and this information is used to asses the legitimacy of their presented character in the interview. Hoopdreams you are correct about hiring for attitude not skill, look as far as the sim ride, where the key to success is improvement, not skill. I think you will find that attitude is the hiring policy of at least one major Australian airline.
