The truth, is that ENTJ's are not really likeable people.
They tend to be rude, blunt, arrogant, too honest, think they're always right, like being the center of attention, talk too much, excessive in many things, and not good at social niceties. ENTJ's are not people you'd really like to imitate because, to be honest, they're not really good examples. They're not leaders as most people think of what a leader should be: rather, they tend to think that they're the authority.
The reason why they do get away with this is because they are well informed and generally make it so that they are actually right and very competent. Just for this, their social utility cannot be underestimated - even though they are not likeable, they are very important for the well functionning of any system.
Having said this, I like them very much personally, but I'm biased.
That sounds extremely ESTJ to me.
As an eNTJ...
I don't take shiz from anyone, but that does not mean I can not be nice and proper when I communicate.
I'm a likable and sociable person. When I am meeting someone, esp for the first time, I make sure that I do it with utter manners. I will hold back on the bluntness, which others might see as arrogant, rude, and "too honest".
Having someone like you, appreciate you, and feel comfortable around you is VERY important. Ease them in on the crazy, it makes life so much easier. Especially for a work/school environment; having a good image, can go a long way with getting people to do what they're told to do. People like to please those they look up to, respect, and like.
Socializing is no necessary by any means, it is merely a tool that is justifiable by result.
I don't believe I am the authority if i'm in a group; in fact, half the time, I don't want to take on the position of leader, because a lot of people do associate being a leader with being an authority, and giving them complete control instead of becoming one unit.
I don't turn people's ideas down as I see fit, I work with them, and they associate me with a leader because I help them organize, schedule, and get the tasks-at-hand done the right way, with minimal presentation of issues.
All that said, I don't put up with incompetence, will kick you in the shins; every now and then my hot-tempered side gets the best of me after I see a lot of mistakes being made. I won't yell, but I will burn a whole into your soul.
