Introduction: System Design Interview Case Studies

1. What This Module Covers

Everything before this point taught you components and designs. This module teaches you the performance.

It holds eight full case studies: seven timed walkthroughs, one per question family, plus the critique form. The critique form is the interview where you are handed a finished design and asked what is wrong with it. Each walkthrough is written the way the hour actually unfolds:

• The question, exactly as an interviewer would deliver it.
• The clock, as it actually runs.
• The follow-ups, as they actually land.
