Cracking the RAG Interview

You know what RAG is. You can explain embeddings, chunking, and cosine similarity without blinking. Then the interviewer says: the correct chunk was retrieved, but the answer was still wrong. What happened? Suddenly, knowing the definitions isn't enough. Cracking the RAG Interview is built for that exact moment. It skips the textbook explanations you've already read a dozen times and goes straight into the real failures RAG systems have once they leave the demo and hit production. Chunks that quietly go missing. Rerankers that make things worse instead of better. Citations the model simply invented. Systems that pass every metric on paper and still frustrate every real user. Through dozens of true to life production scenarios, hands on system design challenges, and one simple framework you will use in every answer, this book trains you to do what interviewers are actually testing for. Not reciting what RAG is, but thinking like someone who has built it, broken it, and fixed it at 2 a.m. Whether this is your first RAG interview or your tenth, whether you are the candidate in the hot seat or the architect deciding who to hire, this is the book that turns "I know RAG" into "I can prove it."
