Ask HN: How to get interviews?

I am currently about 3 years in my career as a developer. I started as a Frontend Developer but now I mostly do Backend. I use Node.js but I have worked with variety of other languages, including Java. I have worked with 2 startups so far and am currently looking for a change, mostly because the current workplace is not very aligned with my career goals. I am from India without a CS degree. I would prefer moving to US or Canada.

I have been scouring tons of job listing websites like whoishiring, AngelList, stackoverflow jobs and applying actively but cannot get interviews lined up. Mostly I would never get a reply for the position and sometimes automated (or possibly not) rejection mails.

All this is degrading my work and I feel like I am not good enough while I know friends who are in the US who have similar work experience as I do getting interviews easily.

Are there things that I can do better? I have started a few projects of my own and will possible make them open source soon but I have heard from friends that it hardly matters. I am absolutely confused.
