I did the Myers Briggs test many years ago and what sticks in my mind the most was my score in the Introvert, Extrovert access. I was literally in the middle. The woman leading the workshop said she'd never seen anyone with my result before and told me to pick I. I do think I skew more to introvert but most of my jobs were more on the E side. And in my job now I just talk to people for my entire shift.
