- Batch vs streaming tradeoffs
- Schema design and data modeling
- Idempotency, backfills, and data quality
- SQL and processing at scale
How to prepare for Databricks's data engineering round
- Match the processing model to the freshness requirement (do not over-engineer to streaming).
- Practice making pipelines idempotent with stable keys and partition overwrites.
- Know how to handle late and duplicate events.
- Run mock pipeline-design scenarios.

FAQ
Does Databricks have a data engineering round?
Yes. In the Databricks loop this shows up as "System / data design": Design data pipelines or distributed processing systems.
How much SQL do data engineering interviews involve?
A lot. Expect strong SQL (windowing, joins, aggregation) alongside pipeline design and a coding round. SQL fluency is usually a hard requirement.
