Good grief, are you all seriously suggesting that someone is going to be materially prejudiced at interview simply because they have a goatee? Even the Navy allows beards, ferchrissakes, and I had a goatee when I got my job in the City (still have, in fact).
So long as you are dressed appropriately, are able to string more than a couple of syllables together and don't dribble on the carpet a little bit of (neatly trimmed) facial hair should not be a cause for either complaint or worry.
