What are the sites with a catalog of real tasks?

Question

Web development

Tell me, how did I see a site on which real tasks from different companies are laid out, which they lay out for a solution in open source, so to speak.
Accordingly, you can decide for yourself and look at the decisions of others.
Interested in real tasks for practice, but preferably focused on a junior middle.
Of course, you can try to freelance to look at tasks and solve them, but it seems to me more useful in such a service to look later at the solutions of others and it is possible to get some kind of feedback on your code.
