Another post here reminded me of a job interview I had several years ago. As part of the application process, they require you to take a personality test. It's the MMPI-2 - well known as a test used to diagnose personality disorders, as well as screen for employment. I think they use it to figure out how well you can cope under stress/pressure and meet deadlines.

My question is this - that test also shows if the applicant could have a mental illness. Is it unethical for an employer to discriminate the mentally ill? Should these types of tests still be allowed as an employment screening process?

The specific job I was applying for was an accounting job at a large corporation.

I do see why some specific jobs require a person who can work well under pressure, or someone who can work well with people, like sales jobs and stuff like that. I don't see why it matters for most jobs.
