Define 'lots of turbine PIC' and a 'good amount of PIC jet'? How much 135 time? What type or aircraft? They like 500 hrs TPIC and REALLY like 1000 hrs TPIC. But in general those candidates are getting hired quicker. Hopefully you have apps in to a half dozen operators who'd be better destination jobs than your current gig?

With 3200 hrs and enough applications out you should be contacted unless there's stuff you're holding back. Maybe not the carrier of your choice but a resume improving, and possible destination job, should find you in the near term. But 4 weeks since you applied is a short time. A regional might call you in a week but that doesn't mean the majors rate your resume as highly as they're getting plenty of 3000+ hr applications.
