I work as a CFI at a Portland based flight school and QXE uses our sim for thier interviews. Several of my friends and fellow CFIs have gotten on with them. The word on hiring is that they are going to slow over the summer to give their training dept time to transition the 200 crews to the Q4. Sept is what I have heard for resuming interviews.
That said if you meet their mins I would get your app in and keep it updated.
Cheers
