DEC's
fatbus, anyone can manage to BS his way around any interview (F/O or DEC), especially if he/she is a sweet talker and has the 'right' answer to any question. As you rightly wrote, what he is really worth is then shown online.
Whether DEC's will be recruited depends on the laws of supply and demand. At the moment EK seems to be finding the numbers by lowering the requirements. However, will the numbers be available in the near future?
