Why have an interview? From most of the work and a little responsibility, to little apparent work and all the resposibility. Some sort of interview would seem appropriate for the extra responsibility, and wider industry consensus is in agreement.
The big question is: why the grilling of First Officers that you know well, and the tea and dates for DEC of whom you know absolutely nothing??
Because if a DEC screws up we can blame the company that sold us a dud.
You are nothing but a herd of cowards.
Why do you have so little faith in your own checking and training system? The answer to that question is even more frightening.
Is there no-one who will take control of the airline's destiny and just fix it?? Just fix it. Everyone but the great big chief seems to know what to do.
Probably better just to leave while the market is strong. There are professional airlines out there.
For those of you who retain little pride...... please enjoy!
