LCI Language Centers interview questions

I submitted my resume' blind (not responding to an ad) and received a quick reply. There were several emails back and forth to set up a time to interview. Setting up the final interview was confusing as the hiring manager did not have good email communication skills. The hiring manager stated a date for the interview, but never confirmed that she received my response to her proposed time/date. The interview was a teaching lesson (15 minutes) to actual students. I was given a topic an prepared a short lesson. This was followed by a formal interview.
