How to use this guide

🗺️Key Takeaways

1
Three learning paths: Beginner (8 weeks), Interview Prep (4 weeks), and Architect (ongoing)
2
Start with Module 0-1 regardless of experience level
3
Active practice > passive reading — do the quizzes, draw diagrams, explain concepts out loud
4
Focus on depth over breadth for interviews; breadth for career growth

Choosing Your Path

Not everyone has the same goal. A junior engineer preparing for their first system design interview has different needs than a senior engineer transitioning to an architect role. This guide supports three distinct learning paths.

Learning Paths

Week 1-2: Module 0 (How to Learn) + Module 1 (Foundations). Build the vocabulary and mental models.

Week 3-4: Module 2 (Databases). This is the most important module — database choices drive 50% of every system design.

Week 5-6: Module 3 (Caching) + Module 4 (Networking). These complete the core infrastructure layer.

Week 7-8: Module 12 (Case Studies) — start with beginner-level: URL Shortener, Paste Bin, Rate Limiter. Practice the RESHADED framework on each one.

💡Study Tips

1) Explain concepts out loud (Feynman technique). 2) Draw architecture diagrams by hand. 3) Take the quiz after every topic. 4) Revisit topics after 48 hours for spaced repetition. 5) Join study groups for mock interviews.

Advantages

•Structured paths prevent wasted time
•Clear weekly goals maintain momentum
•Adaptable to any experience level

Disadvantages

•8 weeks is a minimum — true mastery takes longer
•Self-study requires discipline
