Perseverance my friend.
That is why CX invented the make believe P2X rating and not counting the entire SO time so it is hard to get out.
I would think if you were hired by CX as an S/O then apply to EK as an F/O, it would save EK the interview process. Everyone knows the CX interview process is a painful pedantic.
Good luck.
I'm assuming it's CX but I guess it could be HKA.
