I guess I got lucky in when I started out as a career switcher in 2017. Iirc I applied 6 places, had 4 interviews, got 2 offers. Mind you this was as an effectively junior person applying to mid-level positions. I like to think that having so few interviews allowed me to concentrate my enthusiasm and highest mental energy into the interviews I had, but maybe it's just survivors bias.
Since then I've taken 3 interviews and gotten two great offers in the 50+% percentile for US based software engineering roles. I'm a not-that-bright grug-brained developer, so I'm sure it wasn't because I was blowing people out of the water with my brain power.
I'm not sure I have the energy to do a numbers-game applicant strategy. I hate interviewing generally, and live coding causes my brain to lock-up. So I only apply places I am genuinely excited to work for, and places that I reason would be generally excited to have a good team player who is nonetheless a grug-brained developer.
I can get genuinely excited about pretty run-of-the-mill work though, and have strong opinions very loosely held. I think maybe those two qualities are my secret sauce.
