The 2000 hrs jet PIC could also be to avoid the dreamers who will leave at first sight of a jet-job.
Those with 2000 hrs pic on a jet have learnt - hopefully - that it's about quality of life and other such stuff, rather than about how shiny the plane is. They might end up getting applicants who want the job for the long term instead of some smuck who leaves them at first light with no pilot and loads of problems.
This is pilots own fault. Too many is running for the shiny metal without any wish to do the real flying, so companies need to weed out in the crowds. Looks to me like a company that is actually thinking ahead and planning to employ quality instead of quantity
Good on them, I hope some lucky guy will find he's long term dream job here
