I sent my application may 2011, got shortlisted, went through PSP stages 1 and 2 (compass tests, interview and sim), then my status changed to "PSP successful" but I still had to wait until I got my ATPL unfrozen. Now that it is unfrozen I let EK PSP know it so that I could go on with the final two days of PSP but nothing heard from there since and I'm shortlisted again....
I just hope they don't call me and schedule new interview/compass/sim test dates.....
