I run a (paid) newsletter that sends fun coding interview puzzles every day. If you're interviewing around (or if you just enjoy programming problems), check out Daily Coding Problem: https://dailycodingproblem.com/!

You should've mentioned that email address is required and solutions are $25 a month. But other than that good idea if the actual puzzles and solutions are valuable.

I'm obviously biased but I think the problems are fun and the solutions are valuable. Here are some blog posts I wrote that hopefully give you an idea of our questions:
