A lot of good questions about employment at QR and not many answers. Sounds like Qatar Airways HR department wins the award for the worst communication in the business. Sounds like a disorganised, inept and completely careless group of so-called professionals in their HR department. If they treat wannabe employees this way, perhaps that is an indication of how you will be treated as an actual employee. Inexcusable to not communicate with applicants or those who have supposedly been "offered" employment after a difficult screening process. I hope it improves soon (because it has the potential to be a great flying job) and they hire HR talent from countries other than Somalia...
Unfortunately sounds like a 5-star airline with a 1-star HR department.
