The definitive step-by-step guide to clearing the system design interview at top tech companies.
1
Prep Plan — Learning Path
New to the library? Read the 20-minute article protocol, foundation concepts, and sheet progression before diving into individual problems.
2
Master the Core Concepts

3
Low-Level Design (Machine Coding)
Many top tech companies require a machine coding or object-oriented design round. Learn design patterns and practice clean, extensible code.
4
High-Level System Design — Arch Sheets
Progress Arch 25 → Arch 50 → Arch 75. Each sheet builds on the last with deeper infra, variants, and specialization (AI, fintech, geo).
