You wouldn't necessarily think that you could cheat at a personality test, but it seems the ones that many retailers administer to make hiring decisions for hourly workers are spawning a mini-industry of cheating.

The Wall Street Journalreports (subscription required) that Websites have sprung up devoted to coaching all those would-be CVS Best Buy-salespeople on how answer questions to achieve a "green' score that will lead to a job offer. Since the tests can generally be taken online at home, there's essentially nothing to stop people from cheating. So if you're a sociopathic maniac looking for a job, why not hire your prom queen friend to answer the questions so you can get hired?
