How System Design Interviews Are Evaluated

This lesson explains how system design interviews are evaluated, so candidates can focus on the behaviors interviewers actually score: clarifying requirements, structuring the problem, making defensible tradeoffs, communicating clearly, and adapting when constraints change.

Rather than treating the interview as a test of memorized architectures, Professor Nathan Ward frames it as a collaborative engineering discussion. You will learn what strong signals look like, what weak signals look like, and how to avoid common evaluation traps.
