What is C++?

C++ is a powerful, systems-level language that combines the efficiency of C with object-oriented features. It's used for high-performance applications, game engines, embedded systems, and competitive programming.

C++ interviews test your mastery of pointers, memory management, the Standard Template Library (STL), and performance optimization. You'll discuss RAII, move semantics, and how to write efficient, safe code.

C++ proficiency is critical for systems programming, game development, and high-frequency trading roles. Master the language and you'll tackle the most performance-critical challenges.

Reading answers is not the same as giving them. Sit a full mock interview and get scored on how you actually explain them.
