No surprise. Never have I seen such a poor standard in all my life. Trainers (very loosely termed) who wouldn't qualify for a second officer position anywhere else. Terrible knowledge and ability and huge egos combined with nepotism and corruption. What a recipe for disaster!
Flying through pure "rote" not actually understanding what their doing or why. Just pure blind luck and the reliability of Boeing.
