Software engineering interviews are shifting from LeetCode to "here's a broken codebase, fix it." Things like a RAG pipeline returning the wrong results, or adding a feature to an existing repo. I couldn't find a place to practice that, so I'm building zagoat.

The waitlist just opened and I'm trying to validate before building too much. Would you pay for something like this, or would you just grind on your own? Any advice on pricing for dev tools is welcome too.
