My first MBTI test was back in 2013, and I was typed as an ENFJ.
I retook it in 2017, 2020, and again in 2023. Every single time, the result remained unchanged: ENFJ. I think I’ve recorded a video or two on this before—let me hunt those down and link them below.
The 2020 test was the only instance where I answered questions on camera, which could have affected my responses. That said, I doubt it had much impact since I consistently received the same result both before and after that session.
An interesting fun fact: while traveling in Northern Thailand, someone I met only twice managed to guess my MBTI correctly on the spot. That blew my mind, especially given that ENFJ is one of the rarest types out of all 16!
