Personality tests are really not ok for a multitude of reasons. Almost always are they used to eliminate outliers or fish for personalities which are almost similar to the ones already present. Extremely ironic, as many personality tests emphasize people of different strengths cover weaknesses as long as they don't clash (personal favorite: companies only hiring happy-go-lucky people who won't question things, and then wonder why they critical issues aren't found).

Also, companies who "want to hire for inclusivity" but then eliminate candidates based on a few petty personality differences screams the opposite of inclusivity.
