I have one today. I'm nervous.
I don't think I "show" well.
The I [introverted] in INFJ can work against me, since I go internal when thinking, making me appear guarded - or stupid. Since the world is run by Extroverts, it can be a strike against us Innies.
The N [intuitive] part of me doesn't get all the questions, why don't they just go with their gut? Because that's what I would do.
I did Strength Finder 2.0 (love that sort of thing. I joined e-harmony just to do the personality test. I know, weird).
Intellection (introspective, in other words - Introverted)
Harmony (well natch, I am a Libra)
Restorative (good at figuring out problems and resolving them)
Back to the interview - it's at PROFESSIONAL place. Meaning culture. And not the kind in yogurt.
I have on the required black ensemble (with red shoes!), worried that I'm wearing too much jewelry. (What do you think? two rings, earrings, and a necklace.)
Business casual where I've worked for the past eleven + years involves putting on closed toe shoes, a Hawaiian shirt, and khaki's. Picture Jimmy-Buffet-meets-the-absent-minded-professor.
Pray for me Argentina.
