About Whiteboard Scale

Whiteboard Scale is a free, open practice platform built for engineers preparing for system design interviews. Every topic is a self-contained pack with interview questions, timed challenges, cheat sheets, anti-patterns, and a difficulty ladder.

The goal is simple: give every engineer access to structured, high-quality system design practice without paywalls or sign-ups. No ads, no premium tiers. Just the right problems in the right order.

What you get

• Topic packs - every core system design topic with curated problems sorted by difficulty
• Interview questions - real interview questions mapped to each topic
• Timed challenges - simulate interview pressure with topic-wise timed tests
• Cheat sheets - quick-reference sheets organized by topic
• Visual solutions - step-by-step animated walkthroughs for problems
• Anti-patterns - common mistakes engineers make and how to avoid them
