VJW,
When the advert was posted last October, it was for A330/340 rated guys with over 1000 hours on type with considerations given for A320 guys with similar hours requirements. When the Boeing recruitment opened in december it was for B744 rated and over 1000 hours on type.
I would suggest that all will be revealed in the next advertisement. If it says only airbus rated then you are out of luck, however in the past it has been known to take non-rated airbus people. You will find out soon enough I would imagine.
Good luck
