Well, I can share how I see a INTJ.
-Extremely organized and an over-planner.
-Painfully shy but if you get him talking he can't stop.
-Tortured by the illogical. Spock alert?
-Thinks he knows everything. But it's okay because he does.
-Doesn't outwardly show much variety in emotion. He's not very intimidating when he's mad because of that.
-He always talks exasperatingly about every act of bullshit committed against him. He won't let anything go.
-Every time someone disagrees with him or does not like an idea of his, it's a personal offense against him.
-A great problem solver.
PS: Go INTJs! You guys rock!
