System Design Interview Questions for Beginners

System design interviews reward clear constraints, tradeoffs, and communication more than memorizing one perfect architecture.

Common questions

Design a URL shortener, chat app, news feed, file storage system, rate limiter, or notification system.

Answer structure

Clarify requirements, estimate scale, define APIs, choose storage, discuss cache and queues, then call out bottlenecks.

What interviewers listen for

They want to hear assumptions, tradeoffs, failure modes, and why your design matches the constraints.
