I have actually taken it before, if I remember correctly I was an ISFJ. Whilst I am pretty doubtful about myers-briggs in general, some of it can be quite interesting.

Investigative

The Investigative domain includes careers and majors in science, research, law, medicine, and scholarship, as well other forms of investigative work. This domain is associated with Myers-Briggs Thinking and Intuition. Therefore, Investigative careers are typically not recommended for ISFJs or ESFJs.

Artistic

The Artistic domain entails creative work like writing, music, film, poetry, and literature. This domain can be associated with Intuition, Feeling, and Perceiving. While SFJs may aspire to be creative because of their inferior (or tertiary) Ne function, Artistic careers are typically not their strongest suit.

It's funny how this basically echoes what I already felt. It also helps to explain the frustration I feel at not being able to 'fit in' with more conventional career paths that are typically seen as more profitable. I wonder if anybody else can relate to this?
