Your question is Design a Reusable Research Feature Store. 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).
You are building shared ML infrastructure for a university research environment. Multiple teams train models on overlapping institutional and research data, and they want a common place to define, discover, and serve reusable features without each project rebuilding the same pipelines.
How would you design a feature store for reusable research features?
