An ETL job you own takes longer than the SLA window. Walk through how you would instrument and profile the job (what to measure), how to identify bottlenecks, and list concrete optimization strategies (e.g., partitioning, predicate pushdown, vectorized operations, shuffle tuning). Prioritize approaches by expected impact and implementation risk.
MediumSystem Design
31 practiced
Design a lightweight data catalog to improve dataset discoverability for analysts. Requirements: searchable metadata, dataset owners, table descriptions, schema snapshots, and lineage links. It must scale to ~10,000 datasets and integrate with existing ETL metadata. Describe the key components, storage choices, ingestion/update strategy, and how you would drive adoption.

Tell me about a time as a data engineer when you noticed recurring data-quality issues outside your core responsibilities. Describe the original symptoms, how you discovered the root cause, the concrete technical and organizational steps you took to resolve it, how you engaged stakeholders, and the measurable impact (e.g., reduction in failed jobs, decrease in incorrect rows, or time saved for analysts).
