You know what facility you're chosen for before you go to PEPC. Its up to you to make the decision to accept the PEPC invite. If you get make it to yiur facility and don't like it, then you're just going to have transfer if/when you're able to. This job process isn't full of choices.
Like I've said on earlier posts in different threads, I'm just happy to have made it this far.
That's only true for those of you going to an ARTCC... terminal people only know that they have been chosen for a terminal position and they know what state, but they don't know which facility until they get to the PEPC.
