FYI.
The whole industry is in a bit of a lull at the moment.
Senior instructors are not moving meaning neither are Juniors , The charter world up north would have done the bulk of their hiring a few months back, some companies have shut down, and the regionals and majors aren't doing much.
This happened about five years ago from memory, then all hell broke loose and for about 2 years it was mayhem with vacancies everywhere..
Hang in there, keep applying, call back every month or two if you can develop a relationship with a CFI or CP, and if you can move OS, go for it...
Good luck
