Identify the critical bottlenecks in your high-level design and address them systematically.

Before diving into the interview process, it's essential to understand the key concepts in system design interviews:

Can you calculate storage, bandwidth, and memory needs on a napkin?

A structured framework prevents you from getting lost in minor implementation details, ensuring you cover high-level architectural requirements within the typical 45-minute interview window. The Step-by-Step System Design Interview Framework System Design Interview Fundamentals Rylan Liu Pdf

While finding a compiled PDF guide or reference sheet can accelerate your learning, reading alone will not pass the interview. To truly absorb these concepts, integrate them into an active study routine:

A Load Balancer sits in front of your servers and distributes incoming traffic to prevent any single server from becoming overwhelmed.
