From experince, DON'T go to namibia or bots, you have too many hours and won't fit their mold. They hire the same profile of pilot every year and it ain't a guy with thousands of hours. They WILL turn you down for a guy with 300tt.
Also they say whatever, if they say they are not hiring that doesn't mean if you show up at their door with your résumé they won't all of a sudden be hiring.
Best advice, go to TZ on vacation, if you get a job cool, but don't budget on it.
