I have personal as a CFI taken a job outside the industry while building hours.
When I was instructing full time, I turned wrenches, pumped fuel, took calls in a referral telemarketing sales firm, and worked as a night security guard. We do what we need to do.
I'm squeaky clean, almost have ATP mins, and I get no interest. I've never recieved a turbine job offer.
Airline operations may get you that initial turbine experience. I had seventeen years or so before I got a turbine job. A turbine job may not be your first offer. Or your second.
It's better to take what you can find, rather than hold out for the brass ring. It's easier to bid for the brass ring when you're already working and flying.
