I didn’t start a business but instead made an open source website as no one wanted to or still wants to hire me.

Funnily the website solves the problem of how to learn anything in the most effective way.

Website: https://learn-anything.xyz

and how are you doing since? did the site help in future interviews?

Yeah it does help to get that first interview. Just passing the interview often times means having a good grasp on how to solve LeetCode style algorithmic problems and not necessarily how to build products.

So I am practicing that now and hopefully will pass some interview one day.

I can empathize with your problem. Was just talking to a friend an hour ago about this.

I am wondering whether you have considered companies that don't white board.[1]
