I have taken many Myers Briggs type of evaluations over the years and have always been scored as a dyed in the wool ENTJ. Since my hike- I have been evaluated by two different tests and now have scored as an ENFP both times- scoring lower percentages in the extrovert category than I did before (my introvert is coming out) and also less the thinking and judging. (higher in feeling and perceiving) I find that very interesting. Another interesting thing I heard before the hike- INTJs finish the entire hike more often than any other personality type.
