What the AI Era Edition adds
The free classic covers the fundamentals that never expire. The paid edition goes one step beyond — three chapters on interview skills that didn't exist five years ago. If you're interviewing for engineering roles in 2026, you'll be asked about these.
AI System Design Interviews
Design RAG pipelines, agent architectures, and evaluation systems. The fastest-growing interview category.
Prompt Engineering Assessments
Write, debug, and optimize prompts for production use cases. The new technical screen.
ML Fundamentals for Engineers
Embeddings, vector databases, tokenization, and the RAG vs fine-tuning decision framework. Speak the language.
About Emerson Braun
Software Architect with 15+ years shipping production code, 180+ engineers led, and 500+ technical interviews conducted. I've seen what separates the engineers who ship from the ones who only sound like they do.
AI changed both sides of the table. Companies now screen for AI system design, prompt engineering, and ML fundamentals alongside the classics. Most prep guides haven't caught up. This one has.
The original Cracking the Technical Interview helped thousands of developers — so I made it free, forever. It's my way of giving back to the community that built me. The AI Era Edition is for those who want to go one step beyond.
I also build open-source AI developer tools — including AgentsKit, the JavaScript ecosystem for production AI agents. This work is where 15 years of evaluating engineers meets the new reality of building with AI.
