I know there are great resources out there, and "awesome lists" and so on, and it doesn't help unless you actually put in the effort. However, I'm wondering if there are some resources you prefer, that have a "in-order" list of skills, similar to a skill tree.

This website on HackerEarth gives you an simple idea of how you can progress over time. Is there anything that is like https://www.hackerearth.com/getstarted-competitive-programming/ but a bit more thorough?

Thank you skilled programmers of CodeForces.
