INTP.
Taken it several times (through work) and always come out basically the same. Extreme introversion and strong on thinking; closer to the center on intuition and perceiving.
It’s been years since I read the analysis stuff associated w/ the MB but IRC the category was called The Architect. No huge votes pro or con on the validity of the test but FWIW it’s worth it was interesting.
Fits me well.
