General AI Engineer interview prep

1 live role at Bjak

LLMs, prompt engineering, RAG and AI application development — the fast-growing generative-AI engineering interview at Indian product startups, GCCs and AI-first companies. Distinct from a classic ML engineer: the focus is building on top of foundation models, not training them.

  • Explain how RAG works end to end, from a user query to a grounded answer.
  • What are embeddings and how are they used in semantic search?
