Quick interview answer

Common failures around Chunking Strategies and Embeddings: blocking the hot path, ignoring backpressure, and weak timeout/retry design. Splitting mid-sentence randomly; mixing embedding models in one index.

Detailed answer

Failure modes for Chunking Strategies and Embeddings: Known pitfalls: Splitting mid-sentence randomly; mixing embedding models in one index. • Missing timeouts / unbounded retries • No backpressure when downstream slows • Assuming ordering/guarantees the runtime does not provide How seniors prevent them: Keep embedding model versioned; store metadata (source, date). Parent context: Use Chunking Strategies and Embeddings as the core idea. Example shape: Markdown by ## headers; 512-token chunks with 64 overlap; bge/e5 embeddings..

Full explanation

Name concrete failure modes and the mitigation for each — that scores higher than a vague “it can fail.” Chunk by tokens with overlap, headings, or semantic splits. Embedding model maps text to vectors; must match query/doc language. Dimension and MTEB quality matter.
