Stop Memorizing Algorithms. Start Designing Systems. Most candidates fail AI system design interviews because they treat them like coding problems. To land a role at Meta, Google, or a top startup, you need to think like a technical leader. Master the 3×3 Method —the framework that will help you transform vague prompts into production-ready architectures. What you’ll master in weeks, not months: THINK Like a Senior Engineer: Frame problems using product logic and business metrics, not just code. BUILD Scalable Systems: Architect 25 real-world scenarios, including Recommendation Engines, Enterprise RAG, and Fraud Detection. DEFEND Your Decisions: Demonstrate maturity by justifying trade-offs in latency, cost, fairness, and safety. How the lessons are structured : Each of the 25 questions below is self-contained and includes all the definitions you need to understand the lesson. Where helpful, you’ll also find small prototype code snippets. You won’t use this code in an interview, but it will deepen your understanding of the concept—so you can answer with more confidence. Don't just pass the interview. Prove you’re ready to lead.
