Whenever you're ready, walk me through how you'd approach this.
Can you walk me through a complex data project you managed from start to finish?
Describe the project lifecycle from requirements and source-system analysis through ingestion, transformation, storage, validation, orchestration, deployment, monitoring, and stakeholder delivery. Explain the technologies you selected, the trade-offs behind those decisions, how you handled failures or changing requirements, and how you measured whether the pipeline succeeded.
