Your question is System Design and C++ Readiness. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Be prepared to answer system design and matrix questions, including C++ and general algorithms.
Clarify how you would structure the interview flow, score candidate responses, and support both live and asynchronous evaluation. Focus on what the system must do, how it scales, and how you would keep scoring reliable over time.
