Personality questionnaires ask how you typically think, feel and behave, then score you on a handful of broad dimensions. They do not all measure the same thing. Big Five and HEXACO differ by a whole dimension, Honesty-Humility, which is the reason HEXACO exists. The 16-factor model divides similar territory much more finely, and a type questionnaire sorts people into categories rather than placing them on continuous dimensions. Within one family, the short and long forms do differ mainly in length and in how finely they split each dimension. The short forms give you the broad picture in a few minutes; the long forms separate the narrower facets inside each dimension, which is why they ask so many more questions.
Scores are read against adults generally, the one comparison group held for these instruments. A questionnaire of this kind is not a diagnosis, and it will not tell you whether you are suited to a particular job or course.
