Intermediate Skills:
You will be asked about KPIs, row-level security (RLS) implementation, connecting to multiple data sources, bookmarks, and how to efficiently organize and navigate large reports. Familiarity with concepts like hierarchy creation and data relationships reflects your ability to handle complex datasets.

Advanced Topics:
For experienced candidates, expect questions on slowly changing dimensions, composite models, incremental data refreshes, and integrating Power BI with REST APIs. These demonstrate how well you can optimize reports and manage enterprise-level deployments.
