Your question is Design Experiment Tracking System. 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).
Design a database/system for users who want to record experiments.
Asked in the Technical 2 (System) stage. This was the second part of the system round, after LLM system design involving RAG.
Address the data model, write and read paths, metadata and artifact storage, querying, versioning, concurrency, reliability, and how you would evolve the design for ML-assisted experiment search or analysis. State assumptions rather than inventing unspecified product metrics.
