Interview Prompt

Our data science team has trained several risk models in SageMaker but they go stale quickly because features aren't refreshed fast enough. We need a proper feature pipeline that keeps the feature store current so models can serve accurate predictions at low latency. Design the feature pipeline and feature store architecture.

Summary

The model is only as good as what you feed it.

How This Interview Works

  1. Read the vague prompt (just like a real interview)
  2. Ask clarifying questions to the AI interviewer
  3. Write your pipeline design solution with real code execution
  4. Get instant feedback and a hire/no-hire decision
