For me:

Last August I had 2400 TT, 1200 PIC, 650 IP/EP, and a HPA 73 type and I got the call but then they cancelled all interviews. I just got the call back for a Sept interview with the above plus about 450 hours with CAL on on the 737.

I would agree that seniority means alot (I am getting furloughed by CAL shortly) so if you have your stuff together take the first interview you can get.

FWIW, I got the call after updating the profile (right) side of the app with my new address, don't know if that makes a difference.

Who knows?
