> If you know how to differentiate between those types, or have friends who are of those types, it's going to be hard not to make a close guess.
But it's still a guess. You don't actually know.
But it's irrelevant in a sense. As you say, there are so few types that it's not hard to make a better-than-chance guess for pretty much anybody you meet. As a job applicant, this is no different than what I expect -- the interviewer is going to be making a subjective assessment of me and how well I would fit into the team.
I wouldn't ever take an actual personality test for employment, though, because a company's willingness to engage in straight-up psuedoscience as a factor in making important decisions tells me something important, and unflattering, about that company.
