As far as I'm aware, the hold pool is effectively full. However, I'm sure that some of those in it will need to move on and places will become available. I imagine that the company will let it drop to a certain level (half full?) before it considers it worth organising further interviews. Who knows when that will be. With fuel prices, Open Skies, T5, strikes (now cancelled) and who-knows-what-else, the business outlook must be pretty tight right now. I imagine that recruiting is probably a low priority!
