There is another wholly unrelated issue with the Hogan. It is not necessarily a legal issue, but it could be a PR issue.
The stated goal of the company in giving the test is to insure that future hirees are compatible with previous hirees. A different way of phrasing this is that they want to have procedures that insure a lack of diversity in their Pilot employees. Given that the Hogan hasn't ever been cross-culturally validated, this sort of sounds like someone going to considerable effort to discriminate. In fact, it could easily be made to seem xenophobic by any enterprising young journalist who wanted to count coup on a big corporation.
