I know an ESTJ. I used to hate him because he was kind of a dick, but we're cool now. He was my manager at a fast food place and he had anger issues, was kind of lazy but expected everyone else to work hard (though he insisted he could do a better job), and he thought he was hot shit for being a manager at a fast food place. Later I found out he is a lot of fun to be around, and I can ignore most of his horrible qualities because we have a similar sense of humor, and he's calmed down a bit. I think he was overcompensating or trying to prove something at first.
I know two more. One was a professor of mine. I think I like the female ESTJ better, just because ESTJ energy can be a little overwhelming, and male energy can be a little overwhelming, so the female ESTJ energy can be a bit more understated, or at least slightly less threatening/annoying. I really liked her. She was hilarious (you'd be surprised by what great sense of humor they can have) and spoke her mind.
Lastly, one of my very best friends is an ESTJ. She's like twenty years older than me. She is very hardworking and efficient, and also a lot of fun. Sometimes she is a little overbearing in my opinion, because I am such a feeler and I just don't want to rock the boat, but she don't give a FUCK. She wants what she wants and doesn't take nonesense. She is not shy, and neither am I but I hate confrontation. It doesn't bother her in the slightest, though she is very nice to me.
