The short version
Why the Cplusplus interview is hard
C++ interviews concentrate on ownership. Who owns this memory, when is it released, and what have you accidentally made undefined are the questions that run through almost every round.
What to expect
The rounds you should rehearse
RAII and ownership
smart pointers, and expressing lifetime in the type system.
Move semantics
what a move actually does, and when the compiler elides it.
Undefined behaviour
the cases where the compiler is entitled to do anything at all.
Avoid these
The mistakes that quietly sink candidates
Using raw pointers for ownership when a smart pointer states the intent.
Describing a move as a copy that is somehow faster.
Not recognising common undefined behaviour, which is where the real C++ bugs live.
Reading the questions is not practicing them.
Run a live voice mock tuned to the Cplusplus interview. It follows your answers, probes the gaps, and scores you like a senior interviewer would.
