2. coding-interview-university by jwasham (337K stars)

The self-taught engineer's CS degree.

This is a checklist-based curriculum covering data structures and algorithms, system design, networking, operating systems, and more. It was created by someone who used it to land a role at Amazon without a CS degree.

If you do not have a traditional computer science background, this is your equalizer. Even if you do have a CS degree, this is an excellent refresher before interview season.
