AI-Assisted System Design Interview Guide

Built by engineers who coached interviewers at Meta and evaluated thousands of candidates, this guide prepares you for where system design interviews are heading as companies experiment with AI in the interview loop—and what still separates a “hire” from a “no hire” when an assistant is allowed.

You’ll use AI as a design partner—not a crutch—to explore the solution space, stress-test trade-offs, and sanity-check estimates, while keeping your own judgment on scale, data, and architecture decisions squarely in view for the interviewer.

• A 45-minute structure for system design rounds that allow an AI assistant
• Trade-off frameworks for scale, data, and estimates—now with AI in the loop
• Practice prompts you can run with AI, then pressure-test in live mentor mocks
