System Integration and Configuration Management Questions

Holistic approach to integrating components, managing dependencies, and handling configuration and deployment complexity across environments. Topics include dependency and compatibility management, designing integration tests and contracts, coordinating deployment sequencing, environment specific configuration and secrets management, use of infrastructure as code and configuration management systems, and deployment strategies such as blue green and canary with rollback plans. Candidates should be able to reason about versioning, backward compatibility, release coordination, and operational practices that reduce integration risk and configuration drift.
