I am not that experienced with types... but I'd like to say something too.
During school, I had to work with an ENTJ (it's not a supossition, I actually tested him) on a long term project, which was the school magasine.
He totally thrived on being a chief, no matter how hard the work was. He was inflexible (well, in his mind, he was convinced that he was flexible and openminded) and such a bad people's person, despite the fact he was completely aware of how people thought of him because he talked to them like idiots. If they were not important to him, he didn't even bother to be nice. And that including members of our team.
He absolutely loved making plans and lists and to organize stuff. During this work, I was going crazy, he always asked for deadlines and lists, lists, lists :horor:
What is shocking is that yeah, he was very conceptual, but was simply unaware of how things really were. Just because he had granted a great importance to our project, he simply couldn't realize that for somebody else, it didn't matter...
