So what's next? Genetic testing in case you might be an insurance risk down the road?
Sure, if that is what you and your fellow job searchers are willing to tolerate. If a company wants to do genetic testing you are free to decline any of their job opportunities. Personally, I would not favor my company doing that because it would severely limit the talent pool, which over time would lead to a less talented sales team and less dollars in my pocket.
If you are that offended by the testing, don't take it! You are under no obligation to take a personality test or any other kind of test that offends you. Your potential employers own their businesses and should be left to using whatever criteria they deem appropriate. Like Milton Friedman would say, you are free to choose! And so are the potential employers.
