AI Engineering Interview Prep Pack with Roni Das

150 real AI engineering interview questions, each with a full model answer and a diagram. One PDF: 382 pages and 180 diagrams.

What it covers

Building applications on large language models, from the basics to production: prompt design, structured output and tool calling, embeddings and vector search, chunking and ingestion, retrieval, context management, choosing between fine-tuning, RAG and a different model, offline evals, LLM-as-judge and online evals, guardrails and prompt injection, cost and latency, observability and rollout, and real production failures.

What every question includes
