I applied online. The process took two weeks.

The interview process consists of:

• Two technical rounds with questions on Spark, data structures, and SQL.
• One managerial round with a deep understanding of Spark, Spark 2 vs Spark 3, and a resume discussion.
• One HR round with behavioral questions.
• One 30-minute technical round focused on a deep understanding of Spark and how to handle data quality on large datasets.

The topics included questions on SQL, data structures, and normal ETL in PySpark. There was a discussion on Spark optimisation techniques and the resume. The interview covered how to handle data quality in big data, Apache Airflow infrastructure, and role-based policies.
