I find articles like this interesting. While I have hired plenty of software engineers and data scientists without Computer Science degrees I do think sometimes people without them are at a disadvantage.

Breadth First Search is a freshman year concept at many schools. Sophomore at the latest.

On the other hand it gives me some respect for people who have to learn this all themselves.

I don't think I could have self-taught all of this.
