I was "shortlisted" in the middle of February and have not been scheduled for an interview, although I do still exchange emails with EK. A colleague of mine was "shortlisted" the week before me and has an interview slated for June. But that has been scheduled for a while. If you read up here you will see that EK is backlogged in training with DECs and A380 transitions.
Good luck and see you in DXB.
