Why This Question Matters

This easy-level Cloud/Tools question appears frequently in data engineering interviews at companies like Virtusa. While less common, it tests deeper understanding that distinguishes strong candidates.

How to Approach This

Start by clearly defining the core concept being asked about. Interviewers want to see that you understand the fundamentals before diving into implementation details. Structure your answer with a definition, then explain the practical application with a concise example.

Architectural logic: Global parameters = factory-level; accessible to all pipelines. Local (pipeline) parameters = per-pipeline; passed at runtime or from triggers. Use global for env, base URL; local for LoadDate, table list. Reference: @pipeline().globalParameters.Environment, @pipeline().parameters.LoadDate. Why: Centralize cross-pipeline config; pipeline-specific for runtime. Best practice: Global for env; pipeline params from triggers; secrets in Key Vault.
