When I spoke to my fiancee after the interview, she told me that the whole thing was over very quickly. The security guards were overly stern on the way in, but very polite on the way out.
We were way over-prepared for the interview, and in the end they only needed the I-134 and supporting documents. The consular agent was pleasant and really only asked a few questions before giving her announcing to her "Welcome to America."
