Explain and diagram your past system architecture
System Design Walkthrough: Architecture You Have Built/Owned
Provide a whiteboard-style walkthrough of a production system you have personally built or owned. Your presentation should comprehensively cover the following aspects:
- Problem and Requirements: Clearly articulate the problem the system solves, including both functional and non-functional requirements, as well as any relevant SLAs/SLOs.
- High-Level Architecture: Describe the main components and their interactions within the system's high-level architecture.
- Data and Control Flows: Detail the end-to-end data flows and control flows throughout the system.
- Storage Choices and Data Models: Explain the rationale behind your storage selections and the design of your data models.
- Scaling Strategies: Discuss the strategies employed for scaling compute, storage, and handling concurrency.
- Resiliency Patterns: Outline the resiliency patterns implemented, such as failover mechanisms, retry policies, backpressure handling, and idempotency.
- Deployment/DevOps Topology: Describe the deployment topology, including environments, CI/CD pipelines, observability tools, and Infrastructure as Code (IaC) practices.
- Key Trade-offs and Technology Selections: Justify the major architectural trade-offs made and the specific technology selections, providing clear rationale.
- Evolution of Design: Illustrate how the design evolved over time (e.g., v1 to vN), explaining the drivers and reasons for these changes.
Confidentiality Clause: If you are unable to disclose specific proprietary details about a system, you may present an equivalent system (e.g., a document preview/thumbnail pipeline, notifications, or search indexing) and ensure all shared details remain non-proprietary.
AI interview prep
Core dilemma
The central engineering conflict is not a specific technical problem, but rather the candidate's ability to articulate and justify complex, real-world architectural decisions, demonstrating deep ownership, practical experience, and a holistic understanding of system lifecycle and operational realities.
