It seems that they are swamped with Apps and though they would like to have a first come first served system, they really don't. I first applied in Oct06 (with 1200 TT and 500 multi-turbine) and didn't interview until Mar07. My first App was one of those 'randomly' DQ'd in Dec06 and once I resubmitted it in 02Jan07 they didn't call me until mid-Feb07.
I wish I could give some more specific help, but it seems that repeatedly calling and emailing may eventually get you noticed.
