System Design Interview Preparation

Interview success depends less on memorizing boxes and more on a repeatable method: clarify goals, estimate scale, propose a baseline, stress failure modes, and iterate. This pillar ties the answering framework to concrete designs you can practice end to end.

Audience: Engineers interviewing for senior backend or Staff roles who need timed practice.
