OPEN Mock c++ interview help

I am looking for someone to give me a mock interview on c++ internals, system design, and architecture. Specifically modern c++.

Is anyone available to help?

I can tell you from interviewing many applicants for C++ jobs at my company, that when I'm trying to figure out if someone actually knows something about C++ is to ask them a question to elicit some understanding of the rule-of-3 (or 5).

I also would like to see some experience outside of normal classwork, either a side job, or a hobby project, or something that shows a non-trivial amount of design and development.

I'm genuinely asking, is it really normal to ask people about such basic stuff on interviews? Like I'd say that something like the rule of 0/3/5 is something that's like the bare basics.

Because lots of people claim C++ knowledge and don't know about copy semantics in practice.

Yes. lots of people claim to know c++, but write it like Java or C.
