What does it take to become a junior developer or are companies hiring as an intern?

Question

C++ / C#

I am a student of the Faculty of Physics and Technology. We have almost no programming, but I would like to work as a programmer in the future.

Now I'm learning C++ on my own.
I read 2 books on it:
"Stephen Prata - The C++ Programming Language. Lectures and Exercises"
"Andrew Koenig, Barbara Mu - Effective C++ Programming".

Would like to know what to study next? In addition, I would like to someday get a job as a junior developer or an intern.
I looked at various vacancies. There are many places where knowledge of Qt, SQl, winapi, opencv is required. But I don’t have any ideas about them, and I can’t find manuals on them either.

Could you tell me what to read next, what to study in order to become a junior developer, or did some company take an intern?

Answer 1

But I don’t have any ideas about them, and I can’t find manuals on them either.

With this approach, the battle for the workplace can be considered lost to those applicants who can google the material in 5 minutes.

What do you need.
We need your pet-projects, examples of your work.
