You don't need another 40-hour course. You need to know what's asked, and how to answer it.
Too much material
Two-hour videos, endless blog posts, 300-page PDFs. You watch a lot, remember very little, and the interview is still on Thursday.
Rounds nobody prepares you for
AI and FDE loops now include take-home builds, coding with an AI assistant and a customer role-play. Most prep material ignores all three.
No time
You don't need a curriculum. You need the shortest path to answers you can say with confidence.
Short enough to finish. Deep enough to pass.

Read before you buy
Every chapter follows the same rhythm: the idea in one sentence, the intuition, a diagram or formula, a worked example, and the questions interviewers really ask. See for yourself.
Reading prepares you. Practice gets you the offer.
The Interview Pack turns the book into rehearsal, so the first time you answer out loud isn't in the interview.

Questions
Can I really prepare in one hour?
The fast path takes about 40 minutes: Part 3, the interview questions at the end of each chapter, and the cheat sheet. Reading cover to cover takes a little over an hour.
What format is it in?
A PDF and an EPUB, so it reads well on any screen, including Kindle and Apple Books. The Pack adds the practice workbook (PDF and EPUB), a code repo (zip) and flashcards (Anki and CSV).
Is it up to date?
Version 1.2 was checked in October 2026, with current LangChain 1.0 and LangGraph code and the November 2025 MCP specification. [Your update policy, for example free updates for 12 months.]
Is it for beginners?
It assumes you can code. New to AI? Read it front to back. Already experienced? Jump straight to Part 3.
Can I get a refund?
Because digital files can be copied, sales are final once you've downloaded them. If a file is missing or damaged, or you were charged twice, email us and we'll fix it or refund you. That's why we share free sample pages: so you know exactly what you're getting first.
How does payment work?
Checkout is handled by Gumroad, which accepts major cards and adds VAT or sales tax where it applies. Your download link arrives by email straight away.
