Not sure i fit in the scheme because i work as software programmer, but i have a degree in Telecommunication Engineering and i very liked studying it.
I chose this degree carefully when I was fifteen because i loved math and sciences, then
- I dumped chemistry because i have bad memory for details and my impressions on this course was: a lot of learn by heart and little thinking. (now don't shoot me chemlovers, it was a 15een impression XD)
- I dumped (with some regret) astronomy and earth sciences because I knew how difficult it's in my country to find a related paid job, out of teaching (that i don't like at all)
- i dumped pure math, pure computer sciences and pure physics because, well...they are too pure indeed and I wanted the ability to apply and use what I studied for in creating 'something that finally you can start and run', not only to write an essay on science magazines.
I choose telco over each other engeenering specialization because I am more charmed by energy than by matter (ok, i know it's the same but still...feels different) and by communications issues and oximoros.
I discovered with pleasure that every engeenering course was all on 'putting togheter' very few great principles and apply them in any new way you find useful to solve all problems laid at your feet; and this entairtaining way of studying and thinking was the most 'NT' thing I found in my life...perhaps it's more an INTP way to see the world, so I can't relate it to my INTJ, but I think it's definitely NT at least.
Please, note that in Italy ever the most pratical and down-to-earth paths of study, as should be medicine, are teached in a way far, far more theorical than in USA: I touched an oscilloscope in a school lab only in my third year XD. This must be accounted for in my choice to 'dumping' the more abstract courses.
Other:
Of all my former fellow students, I know the MBTI types of only 3 (freshly tested) and they are 2 ISTJ, 1 ISTP. All three changed path of studies before they could fulfill all the exams: one took a degree in statistic, one switched for the army and the ISTP opened a night club.
