Gen AI Engineer Interview Kit

The 2026–27 edition of the Gen AI Engineer Interview Kit, rebuilt from the ground up as a three-volume book for GenAI Engineer, Applied AI Engineer, LLM Engineer and AI Agent Engineer interviews.

What's Inside

Volume 1 - The Question Bank

166 interview questions on transformers, embeddings, prompting, RAG, agents and MCP, evaluation, fine-tuning, inference, security and multimodal systems. Every answer follows the same seven-part structure: what the interviewer is really testing, a 30-second answer you can say aloud, a deep answer, follow-up questions, the weak answer that sounds right but fails, and what a senior candidate adds.

Volume 2 - The Rounds

Everything beyond the Q&A:
• Estimation: KV-cache size, GPU fit, serving cost
• 14 production-debugging scenarios
• 16 full system-design cases
• 24 live-coding solutions, every one tested
• The human rounds: project deep-dive, customer simulation, eval design, AI-assisted coding
• 3 scripted mock interview loops
• Job-search, resume and negotiation playbook

Volume 3 - The Builds

8 portfolio projects you build, run and defend in an interview:
• A tiny GPT from scratch
• A cited RAG take-home with an evaluation set
• An LLM-as-judge eval harness
• A multi-provider LLM gateway
• An MCP tool-using agent
• Text-to-SQL
• A prompt-injection red-team lab
• QLoRA fine-tuning on an 8 GB GPU
Each comes with working code, tests, measured results and resume bullets. Everything runs on free-tier APIs.

Why This One

• 240 questions answered in depth, plus 448 follow-ups
• Every code example was run before it went into the book
• Every number was measured or computed, never guessed
• Each question is mapped to the round where it comes up
• Company-specific questions are marked as reported, with sources
• Models, prices and limits were checked in October 2026, and dated so you know exactly how current they are

Who This Is For

Engineers with intermediate Python who have built something with LLMs, or are learning to, and have interviews coming up. Includes 7-day, 30-day and 8-week study plans.
