They all took their time.
One that seemed promising rejected me over a botched take-home-project.
Another one didn't talk to me vor over a month, then cam suddendly back with a "yes".
All felt pretty uncertain until it worked.
After that I got better in those kind of interviews. Knowing what to say and what not.
At one point I started blogging and that helped with telling people what I know (just read my blog).
Now, I write articles as my main job, lol.
I wrote some articles about topics I worked with. React, Webpack, JavaScript, etc.
I think, I was lucky in many ways.
I started blogging 2017 at dev.to when everyone with a name was blogging at medium, so there wasn't much competition.
I wrote beginner articles about front-end topics, that hit a nerve. So getting in the top 7 post of the week a few times helped with motivation.
I posted almost every week in 2017.
Took over two years until companies wanted to pay me to write for them.
