Hey, I'm one of the right seaters on their Dallas facility.
You'll have a good chance of getting hired as long as you have your ATP and some experience teaching. Turnover is very high here in DFW. Very few people stay over a year. Most leave to persue jobs they made through contacts while instructing. The main complaint I hear is they get burned out by flying the same profiles day in and out (mostly approaches into JFK). Schedules seem to vary. They try to set it up where you have several days on, followed by a standby day, followed by days off. Most instructors seem to work their standby days. During busy times, after initial classes, be prepared for late night work The job postings they put out (see their website) says starting wages are about $55,000. I don't know the specifics of their benefits, but I haven't heard people complain about them, so they must be decent!
