Half the problem for experienced guys who are getting turned away and trying their hardest to get into the airlines is HR.
If you don't tick some little box that HR has come up with you don't get the job. No matter how well you did in your SIM or Group assessment. They are turning away very experienced people who would not have any issue slotting in to the right seat of a jet (Including me), people who are already proven in the right-seat of a regional sized transport category aircraft.
