It seems odd to me to call this "open source" when I can't find a statement of license or copyright on the site (maybe I missed it?).

I would expect something like a Creative Commons license to make it clear what can be reused and under which conditions.

It's under MIT: https://github.com/oleg-koval/counter-interview.dev/blob/mas...

But yes, this should me more explicitly mentioned if they are advertising it as "open-source".
