I was 37 with about 350 hrs GA (no instructional background). First job with regional TP operator. Second job year later on BA Airbus.
I had no particular line of enquiry other than applying to everyone over and over and over again! I must have sent 3 or 4 cvs to first employer before I got interview. Interestingly, as soon as I had one interview, 3 more came along within 2 weeks. Interviews - like buses.
