They know a fair % of pilots will be leaving, just not exact numbers, fleets, seats or bases. Its all very fluid. They have had problems with training capacity, no point recruiting more than they can reasonably train, type rated needs less training, recruiting a direct entry skipper reduces the training needed, but annoys the hell out of internal command applicants.
From old colleagues who work there, if you get a base close to home it can be an "Ok Job", but I haven't spoke to anyone flying there with a good word to say about the company culture. Everything is done on the cheap, and that is not always best value in the medium and long term.
