In a perfect world, job interviews ask for assignments like CodeCrafters instead of Leetcode. The best way to refresh your programming language skills and learn something new about Redis, Git, SQLite internals.

Found out from a colleague. It has you build your own version of things like Git and Docker from scratch. A cool way to build a stronger mental model of how those tools work.

I’ve started the SQLite challenge, enjoying it a lot so far. Just the right level of guidance, helpful yet gives you a lot of freedom to explore and learn for yourself.

The Redis challenge was extremely fun. I ended up having to read Redis protocol specification doc pretty carefully in its entirety! The result felt like lightly-guided independent study, if that makes sense. (Which, again, was lots of fun)

The challenge helped me dive into its internals, through *actual* practice. Super fun.

I was really impressed that they support Haskell, and will probably usethis to learn Rust! The git-based workflow is :chefkiss:

I'm learning about how Redis works under the hood, system calls, socket programming in Python — something I've never done before
