First of all, thanks for all of the advice. The hiring guy had the tact to not bring up our prior encounters, and I managed to maintain good eye contact and use big words when I spoke. I endured 45 minutes' worth of what-would-you-do-in-this-scenario type questions β€” seriously, it looked like he was reading from a short-answer exam β€” and I think I did rather well when all was said and done. Success!
