In what order should I learn C++? Difference between junior/middle in C++?

Question

C++ / C#

Good afternoon!
I decided to make a plan to study the necessary skills for getting a job as a C ++ programmer. But I ran into the problem that there are no clear criteria as well as areas of activity, it all depends on the company. So in one they require an understanding of the operation of video codecs, in the other, knowledge of UE4 / blueprints. Is there any C ++ developer map by analogy with https://edu.cbsystematics.com/Ru/education/roadmap or any other infographic.
I am also interested in the difference between junior / middle. But I think the infographics will make everything clear

Answer 1

Learn pure C++ first, then either qt or .net.
And between junior and middle, the difference is only in experience

Answer 2
