ANN search, hybrid retrieval, and scaling to 500M vectors — system design for vector DB interviews.
Vector database interviews blend ML fundamentals with classic system design. You'll need to explain ANN algorithms, hybrid search, index tuning, and how to scale retrieval to hundreds of millions of vectors with sub-100ms latency.
These questions mirror what teams at Uber, Airbnb, and Pinecone ask senior infrastructure engineers.
