25 questions

01How would you create an enterprise strategy for RAG architecture across business units?

A principal-level answer

Say this first: Retrieval-augmented generation fetches relevant, approved context at answer time so a model can ground its response in current source material.

Use a real scenario

Imagine an internal support assistant that answers from approved policy documents. The team must decide how to apply RAG architecture, verify the result, and explain the user impact. For a RAG Engineer, attach the explanation to an evaluation set and retrieval trace.

Show judgment

  • set decision rights, investment thresholds, and risk-based governance without centralizing every choice.
  • State the constraint that could change your decision, such as scale, data sensitivity, recovery target, or team ownership.
  • Call out prompt injection and unsupported answers and the control that reduces it.

Evidence to mention

Track grounded-answer rate and p95 response time. Say what baseline you compared against, what would trigger a rollback or escalation, and who owns the follow-up.

request or change → guardrail / validation → RAG architecture → observable result → owner review

Practice prompt: Tie the standard to customer impact, grounded-answer rate and p95 response time, and a review cadence.
