Opening excerpt (first ~120 words) tap to expand
# Introduction Even as AI can now generate huge amounts of code, system design remains one of the few skills that cannot be easily replaced. Writing code is only one part of building real products. Designing scalable, reliable, and efficient systems still requires experience, trade-offs, stakeholder discussions, and strong engineering judgment. That is exactly why system design continues to matter so much in technical interviews. It is not just about knowing the right answer. It is about how you think, how you break down complexity, and how you justify your decisions. For many engineers, this is also one of the hardest parts of interview preparation because it demands both technical depth and structured communication.
