The interview process included an initial screening followed by a technical L2 discussion for a Senior Data Engineer role. The technical round was broader than only SQL and included practical data engineering topics such as SQL problem solving, data warehousing, data modeling, data governance, data validation, ETL pipeline design, and production-oriented scenarios. The interviewer also shared a few live SQL-style questions through chat, including consecutive purchase detection, sessionization, triggers, and splitting comma-separated values. Overall, the interview was challenging and focused on real-world data engineering understanding rather than only syntax.
