Ask HN: What is best way to do hands-on practice for system design?

I think practicing design is difficult because of one major issue: how will you know if you got it right? I think the only way is to actually implement the design, and learn what works and what doesn't (and, crucially, why).

It's essentially an apprenticeship: you work in teams and as you gain experience, you contribute progressively more and bigger ideas. One day, you get a job where the design is your responsibility.
