ESTps are often good salesmen, where their inclinations are best used in technical sales where they can be persuasive but also using logic. I have known a few and I worked very closely with one. The logical subtypes would generally be best, however, the sensory subtypes will look annoying and "trying to ram the product down the customer's throats" to some people, without noticing.

But I guess this is included in "business".

Other real examples I am aware of personally, and not in business --

- professional scuba diver working for the police (recovering corpses etc) - a job that would fit FDG's criteria, I think - not regular hours (but this is a bit of "sports" and "crime", in a way)
- Hollywood cameraman and TV producer
- PhD chemist (a girl)
