Agree with this. Tech is
everywhere so finding an edge with domain knowledge will make you standout compared to all the other folks looking to get into it with no professional experience.
I'd suggest targeting a few companies a week and doing research. As a (former) hiring manager, it is so much more powerful for me to get a message like this:
"I was reading your company blog post about the resurgence of vinyl. It was really interesting. I sold all my vinyl in the 2000s, but have noticed it coming back at my local record store.
I also saw that <company> is using golang and typescript, based on your job descriptions. I've used golang and really enjoyed it; I found the abstraction of channels made it really easy to communicate between different components.
I was interested in applying to your engineering team. I have a lot of music experience and some tech experience. My resume is attached. I'd love to chat if you are interested in seeing if there's a mutual fit."
Than one like this:
"I was looking at your site and thought you might like to hire me. Resume attached."
Doing just the slightest bit of research (30 min) will, again, make you stand out in a sea of resumes. (Of course, a warm intro is even better; LinkedIn can help you find out if you know anyone who knows anyone.)
