Structured System Design Frameworks for Platform Engineers
Introduction
In this lesson, we will explore how to approach system design interviews from a platform engineering perspective. Unlike standard software engineering interviews, platform interviews focus heavily on infrastructure, scalability, reliability, and developer experience.
The Framework
When presented with a platform design problem, follow this structured approach:
- Requirements Clarification: Understand the scale, scope, and non-functional requirements (NFRs).
- High-Level Architecture: Draw the major components (e.g., API Gateway, Kubernetes cluster, Database).
- Deep Dive: Discuss specific technologies and why you chose them (e.g., Kafka vs. RabbitMQ).
- Failure Scenarios: Discuss what happens when components fail and how the system recovers.
Conclusion
A structured approach ensures you cover all bases during a high-stakes technical interview.
