I think they can be good in some contexts. My friend works at a company that gives an in-depth one post-employment that gives a person's 2 dominant personality traits. Everyone is educated on each; eg. strengths of each personality, pet-peeves of each, role in group tasks. And they get a sticker with their personality type to put on their hard hats. It sounds hokey, but as an INTP, which is a less desirable personality type which is less frequently experienced with others, it might be helpful to others to be reminded that INTP/INTJ people aren't snobs or autistic.    On the other hand, a pre-employment personality quiz asked me Would you feel comfortable working in an environment where Arabic is spoken? Not reading between the lines, I answered no, because my thought was primarily that I don't understand Arabic. In reality I was probably being screened for Islamiphobia    The true-false questions and the 1-10 scale questions are the hardest. If someone answers false to I am always the best at what I do, are they saying they're not a doucebag or are they saying they're probably going to be the most incompetent person there? 1-10's would seem easier, but in reality anything between 3 and 7 is counted as an invalid answer. If asked, I'm always a happy person I'm going to probably say 6...generally, I feel the expected range of human emotions about various things. Essay or short-answer questions, or a space to show one's work would be more appropriate.
