Your question is Project Walkthrough and Contributions. 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).
Walk me through your previous projects and your specific contributions to system architecture.
Focus on one or more projects involving an end-to-end ML system. Explain the requirements, scale, architecture decisions, your ownership, tradeoffs, deployment approach, and how you evaluated and operated the system. Be precise about what you personally designed or implemented versus what the broader team delivered.
