Dear @kitszu – I checked and that site offers a free test indeed.
Takes about 15 minutes, but I am not sure it is identical to Myers Briggs. They say it is a Jung personality test based on the work of Myers Briggs.
Took that test and apparently I am an ENFP:
ENFPs are both “idea”-people and “people”-people, who see everyone and everything as part of a cosmic whole. They want to both help and to be liked and admired by other people, on both an individual and a humanitarian level. This is rarely a problem for the ENFP, as they are outgoing and warm, and genuinely like people. Some ENFPs have a great deal of zany charm, which can ingratiate them to more stodgy types in spite of their unconventionality.
Who would have thought. :-)
