Intro

System design interviews can be a challenging and nerve-wracking experience, especially for engineers who have little experience with the process. One way to prepare for a system design interview is by using a standardized template that can guide your thinking and help you organize your thoughts. In this article, we'll be discussing a template that can be used to structure your responses in a system design interview, and how to use it effectively to impress your interviewer.

Template

Brief about the problem
