| Interview rounds | Technical screen, SQL or systems, database design, behavioural and team fit. | Technical screen, Spark or distributed systems, data design, behavioural and committee-style review. |
| Core depth | Warehousing, query execution, storage layouts, concurrency and governance. | Spark, Delta Lake, MLflow, lakehouse patterns and large-scale ETL. |
| SQL depth | High, with optimisation, joins, windows and query plans in focus. | High, but often paired with Spark dataframes and distributed execution. |
| Pipeline design | ELT, data sharing, warehouse cost, governance and data products. | Batch and streaming ETL, bronze-silver-gold layers and cluster performance. |
| Behavioural framework | Teamwork, customer focus and enterprise judgement. | High technical bar, ownership and communication under complex tradeoffs. |
| Take-home | Possible by team, but live technical rounds are common. | Possible practical data exercise, team dependent. |
| Offer typical TC | High public-company data platform packages. | High private-company packages with IPO and equity assumptions to inspect. |
