Udemy – System Design Interview for Backend Software Engineers

System design interviews are rarely difficult because you know nothing about backend technology. They are difficult because you must turn an ambiguous prompt into a structured conversation, make decisions with incomplete information, and explain why your architecture fits the problem.

This focused course gives you a repeatable process for moving from a blank whiteboard to a clear, defensible system design. In about four hours, you will learn how to clarify scope, identify functional and non-functional requirements, make back-of-the-envelope estimates, define API and data contracts, sketch a high-level architecture, investigate bottlenecks, and discuss resilience.

What you will learn:

• Structure a system design interview from the first question to the final trade-off.
• Design and explain APIs, data models, traffic flows, and scalable backend architectures.
• Evaluate performance, reliability, security, consistency, and operational complexity.
• Recognize bottlenecks and choose practical techniques for handling scale and failure.
