Having arrived in the area rather early, I toddered about for a bit before entering the building 10 minutes before my scheduled interview. This seemed to catch the primary interviewer rather off-guard, but he recovered admirably as I sat about for twenty minutes. Following that, it was really a pleasant chat with two potential superiors about the position's remit, the company's books, my own interests, and of course my relevant experience. It was rather evident by this point it probably wasn't a splendid fit, but I went ahead with the brief skills test anyway, bid them a good day, and left, no more than ninety minutes having passed.
