I test as ENTP at work and INTJ at home just because success at work requires a different mindset. I don't like it, but that's how it is.
Also, ENTP & INTJ all that stuff is proven to be bunk with no statistical evidence that it predicts anything.
I'm also required to represent my company's interest instead of lending a sympathetic ear to a friend. Don't get me wrong: I'm honest and fair, but some avenues are simply closed in an employee / employer relationship.
I just told a guy today that he flunked an interview because he failed to convince the ED he interviewed with that he (the interviewee) would adequately represent his area on a P1 production support bridge.
I could have sugar-coated it and said "Ah, man, yeah that was unfair because I've seen you succeed in exactly that situation" but instead I coached him on how to present himself better and (hopefully) pass the interview next time.
It wasn't pleasant telling him what I had to tell him, but it was necessary.
No arguing with that.
In the long run, we can hopefully select against business practices that have these kinds of human costs.
