What this interview will probe
Build the next-generation distributed storage and processing engine on the Runtime team, contributing to Apache Spark, Delta Lake, and the data-plane services and query optimizer behind the Databricks Lakehouse. The work is deep systems engineering on petabyte-scale data over cloud object stores like S3 and Azure Blob. A technical interview would probe distributed-systems and database internals, query execution and optimization, and concurrency and performance engineering in Scala/Java on large datasets.
