Answer 2

Hello, you can test your competence here https://ruby-challenge.com/en/grades/backend-junior . The guys from evrone have compiled a list of what a rubist should know at certain stages of their career, and you can also take their challenge.

There are no clear criteria.
My personal opinion, which is shared by many, is that middle and junior do not fundamentally differ in skills, they just do everything better and better.
