I really though too much of it. I thought it was going to be an interrogation in a small office. But it wasn't what I thought it wouldve been. You get called up to a window cubicle type thing and the interview (not formal feely) was held through this plexi glass window.. They are really friendly at the Vancouver US Consulate. Have no fear. However, I now fear my AOS interview at the Seattles USCIS. Good luck to me.
