Interview Prompt
Our company is starting fresh with Databricks as the core data platform. We have six data sources that need to be ingested, transformed, and exposed through a consistent semantic layer for business analysts. Design the end-to-end platform architecture - including infrastructure-as-code configuration for each source, the orchestration DAG, and how the semantic layer sits on top.
Summary
Infrastructure as code. Meaning as a service.
