Your question is Secure Enterprise Search with Permissions. 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).
How would you architect a secure enterprise search system that respects user-level document access permissions using vector search?
Explain the end-to-end design, including document ingestion, authorization modeling, embedding and indexing, query-time retrieval, ranking, serving, and auditability. Address how you would prevent unauthorized documents, metadata, snippets, or embeddings from appearing in results, and how you would handle permission changes, revocation, tenant isolation, latency, evaluation, and failure recovery.
