Many pilots work at Flight Experience as a "second best" alternative to actually flying for an airline. The irony is that they treat it like a real airline job, with swarms of wannabes sending in their resumes so that they can go to work wearing a pilot's uniform. They forget those are not flight hours which you can write in your logbook. Some even treat it as a step for launching into the right seat of jet, although in reality it may never happen. And the boss exploits this vulnerability and pay them peanuts. As for non-typed instructors, it's the blind leading the blind.
Not shooting down Flight Experience as an organisation - it's the pilots' attitude which is the main problem.
