• Deployment Strategies – Implementing blue-green, canary, or rolling deployments to minimize user impact during updates.
• Advanced concepts (less common) – GitOps workflows using tools like ArgoCD or Flux, and automated pipeline verification using synthetic testing.

Example scenarios:

• "Walk me through how you would configure a GitOps pipeline to automatically deploy changes to multiple Kubernetes clusters globally."
• "A deployment pipeline is consistently failing during the integration testing phase. How do you isolate the issue between the infrastructure, the test suite, and the application code?"

Systems Design & IoT Scalability

Because Sonatus works with connected vehicles, your systems must be designed to handle massive, unpredictable spikes in data telemetry. This evaluation area tests your ability to design high-throughput, resilient architectures.

Be ready to go over:
