Well, my sample size is small (INFJ: me and a CTO at a different company, INTJ: two colleagues) and my MBTI knowledge based mainly on
https://www.16personalities.com. I'd still say it can fit quite well because:
- Introversion: useful for working on the kind of technical tasks outlined in the article instead of preferring to work with other people (apart from the customer success example).
- iNtuitive: coming up with out of the box, ad-hoc ideas to solve whatever new challenge is there.
> When there’s a need for innovation or a different perspective, people with Intuitive personality types can usually step up and provide a new direction. Practicality can sometimes be overrated, especially when a situation calls for serious change and “coloring outside the lines.” [1]
- Feeling: Yeah here I agree that „Thinking” types would suit better according the core theory. But when put in contrast to INTJ, I think that's the dimension which can cause someone to become a wildcard in the first place instead of a specialist: wanting to help everyone else in the company rather than focusing on more clearly confined problems for a long time.
> morale killers for these personalities may include strict rules, formal structures, and routine tasks. They may find it especially dispiriting when they’re asked to redo their work, particularly if it’s for a reason that just doesn’t seem valid to them. [...] At times, efficiency may be less of a priority for Advocates than collaborating with and helping colleagues who need a boost. [2]
- Jugding: I agree that „Prospecting” suits better according to the theory.
So overall, INTP seems to be better suited by theory. But in practice, INFJs are also drawn to the wildcard role and can get quite good at it.
[Edit]: Re-reading the article, especially the „wildcards in summary“ part is a very close match with „infjs at work“ (unknown challenges over routines, importance of impact, creative and independent problem solvers)
