Whilst Flybe might not seem that great to an outsider, it really isn't that bad an employer when compared to some outfits out there. Yes there are issues, but there are issues in every company is there not? Yes people are leaving, and I'm one of them, but I've had 9 good years at Flybe and I wouldn't change my time there. I've got a fantastic job which I love, but it's time for a change for personal reasons.
As for "don't touch with a barge pole", I don't think there's any credence in saying that at all, particularly if you've never worked there.
Direct entry commands are happening as we speak.
PPJN is about up to date with pay.
Roster - you'll be worked to EASA FTLs, it's a target, not a limitation.
Time to command - depends how many hours you have, but you generally need 500 with Flybe, and the command process has just got even harder. If you have 200hrs then expect just over three years.
