LISMA Language School interview questions

Showed up. Interviewer had not read my resume and knew precious little about my job history. Despite showing her I am presently hired and working part-time as an adjunct for a major university, she repeatedly asked whether or not I was an English teacher. She didn't present the school at all, no tour, no basic overview of how the school works. The only info I got was after I asked questions about the class size, curriculum , student body, etc. The job listing posted 30.00 and hour as an offer, but once I said I wanted this as a salary the interview concluded quickly. Overheard students talking to desk staff, and the morale at the school seems low and I'm guessing there is a very high turnover rate here. I asked about paid prep time--teaching a 4+ hour class requires a bit of prep time, but this question seemed viewed as unreasonable. This school is very clearly a struggling VISA factory.
