ANSWER:

If these tests are scientific and based on observation of the behavior of an individual and checking his positive and negative inclinations and observing his actions, reactions, feelings and statements and then building a scientific profile based on facts, this is permissible in Sha Allah. But if it is based on analyzing his hand writing or facial expressions or the likes, this is prohibited and part of soothsaying. 

Is it permissible to do personality types test such as Myers Briggs (MBTI)?
