Over the last two years I have applied to at least 150 jobs. For each application which would accept a cover letter, I wrote one. And I only applied to roles which I really believed I would fit into - I didn't just spray and pray.
I think I've had 4-5 companies that I got to interview with. The closest one to hiring ended up choosing another guy who had a little more frontend experience (this was for a backend role). But they said they really liked me. That's great, but it doesn't help :)
The rest were usually silent rejections. I'm actually grateful when I receive a rejection email (vs indefinite silence).
Along the way, I've built maybe 8 demo projects as part of the application process. I got to show off a few to the companies, and despite delivering what I honestly believe were clean, quality solutions, I didn't get the jobs.
Eventually I gave up applying for some months. It's just to demoralizing to keep trying and getting nowhere. Now I build things that make me happy (for no money), like my new web game, Vector Defense -> https://michaelteter.com/vector.html
I've started applying to companies again. If nothing happens in the next six months, I'll most likely walk away from my tech career and just get a "regular job". Maybe I'll open a gym in Bangkok; they don't have many, and the few decent ones have surprisingly high monthly fees. I could compete; and I love hospitality and providing nice experiences for people. So if anyone wants to partner with me, hit me up!
Good luck in your search!
You have to have some affinity to religious/Christianity/church topics, otherwise it’s quite a turn-off.
