Common Interview Questions#

1. "Why do LLMs hallucinate and how do you mitigate it in a clinical system?" → RAG + citation grounding + validation + human review
2. "When would you choose RAG over fine-tuning?" → Knowledge is dynamic, citation required, institution-specific → RAG
3. "Design a RAG system for a hospital's clinical guidelines" → See full system design in interview/architecture/01-design-enterprise-rag.md [PLANNED]
4. "What is RAGAS faithfulness and why does it matter for clinical AI?" → Measures whether claims are grounded in retrieved context; most safety-critical metric
5. "How does the context window affect RAG architecture?" → Creates retrieval budget; "lost in the middle" → order matters
