I had two colleagues once who were officially tested.
The ESTJ ran the office when the boss was away, preocupiednwith getting shit done and keeping thibgs flowing. She was utterly petite, yet had no problem removing a 6'4'' muscled, disgruntled and possibly aggressive guy from our officenwith just a stern voice and steely attitude.
She was utterly polite and a trained psychologist so she did focus on people as it was her job but the job always came first, as did optimizing the organisation. She was a go getter in terms of following up leads and getting customers and during a crisis she d have a cool head and revert to the 'manual', using logic and rules to solve and determine the best course of action based on precedent.
Interestingly, she liked details only in that kind of situation. When a big project for the city came in, which she helped develop the lead on, we had to send in an offer. I saw her look at the guidelines which typically are quite anal and robust, and groan. She had no patience for it as it would suck up hours to follow to the exact specifications.
She showed it to the istj, who lit up like a christmas tree. Like the estj, she liked doing a thorough job and competition. Bur she especially loved the idea of putting together in exact detail an offer that was perfect for landing us this great client. The idea of being in her office, alone, with this perfect puzzle and a carefully constructed manual on how to achieve this perfection and earn a cookie, so to speak - aka the prestige/pat on the back for landing a big client, was pure bliss, and something that fit perfectly in her wheel house. And she did get us that client, i believe
