Try a sample question
A knowledge graph built from company earnings reports contains nodes for companies, products, and executives, with edges like 'CEO_OF' and 'LAUNCHED'. A query asks 'Which companies did the CEO of Acme Corp previously lead?' Why does this query benefit more from graph traversal than vector search?
A.Vector search cannot handle queries about people, only about products and financial data
B.The query requires following a relationship chain (CEO_OF → person → previously_led → companies) that is explicitly encoded as edges in the graph, which vector search cannot traverse since it retrieves semantically similar text chunks, not relational paths
C.Graph traversal is always faster than vector search for any type of query
D.The query uses the word 'previously' which vector embeddings cannot encode temporally

Frequently asked questions
- What does the GraphRAG & Knowledge-Graph Retrieval check test?
- The check covers when vector similarity is not enough: entity/relation extraction, leiden communities, hierarchical summaries, local vs global queries, and when graphrag beats vector rag.. Questions span beginner to advanced difficulty and test both conceptual understanding and practical trade-off reasoning.
- What keywords should I know for GraphRAG & Knowledge-Graph Retrieval?
- Key concepts include: GraphRAG, knowledge graph, entity extraction, Leiden, community summaries, map-reduce RAG, Neo4j, Microsoft GraphRAG. These frequently appear in rag & retrieval systems interviews at product and infrastructure companies.
- How many questions are in the check?
- Each check has 10 questions — a mix of MCQ and short-answer. You get scored by dimension (e.g., scalability, consistency) so you know exactly where to focus.
- How long does it take to study GraphRAG & Knowledge-Graph Retrieval?
- Most engineers spend around 3 hours on this module. The check itself takes about 10–15 minutes. You can retake it up to 3 times per day.
- What prerequisite knowledge do I need before GraphRAG & Knowledge-Graph Retrieval?
- GraphRAG & Knowledge-Graph Retrieval builds on Advanced Retrieval Patterns and Agentic RAG. Complete those first for the best results.
- Is GraphRAG, knowledge graph, entity extraction covered?
- Yes. The GraphRAG & Knowledge-Graph Retrieval module covers GraphRAG, knowledge graph, entity extraction among other key concepts. The check includes questions that reflect real rag & retrieval systems interview patterns.
