hey refugee
Your situation is very odd, because me and my group interviewed for DEC about 3 months ago and we all already received the email stating that we passed the selection (that took 3 weeks), the job offer and fleet allocation ( took 4 weeks for the last guy who received it ) and one has already is DOJ ( beginning of July on the 777 ).
If I were you I'll give them a call and check the spam box on my email because too much time has passed, my friend!
Good luck
