So it means than 99% (at least) of the ex-Alitalia guys who attended the DLR, Sim, final interview...and didn t get the job do not have the prestigious skills of the"Europe s leading company"???
No.
It means that they did not meet the narrow profile the Lufthansa management is looking for.
Sorry to hear about the guy didn't pass the final stage. But it's part of the game, try to change point of view: you had a good experience and this will help your next selection process.
