Knew the basic components but kept second-guessing how deep to go on the build artifact storage vs the orchestration layer.
Start by clarifying requirements and constraints, then design a scalable, secure CI/CD pipeline that supports Apple's scale and AI workloads. Focus on key components like build, test, and deployment stages, and discuss trade-offs around speed, reliability, and security.
Pro tip: Emphasize incremental improvements and observability—show how you'd measure pipeline health and iterate, rather than aiming for a perfect one-shot design.
Ask about scale (number of builds/day), supported languages/frameworks, security/compliance needs, and integration with existing tools. This ensures your design addresses real constraints.
Outline the main components: source control integration, build system, artifact repository, test orchestration, deployment mechanisms, and monitoring. Sketch how they interact.
Pick 1-2 areas to detail, such as distributed build caching for AI models, secure secret management, or canary deployments. Explain how you'd handle scale and failures.
Compare options like monorepo vs. polyrepo, self-hosted vs. cloud runners, and synchronous vs. asynchronous pipelines. Justify your choices based on requirements.
Recap the design, highlight how you'd measure success (e.g., build time, failure rate), and propose next steps for improvement.
