Walk me through how you implemented row-level security in Sigma for a multi-tenant or role-based reporting use case. How did you pass user attributes into the security filter, where did the access logic live — in Sigma, the warehouse, or both — and what broke when you tested it with edge-case users?

A Sigma dashboard is timing out for executives on Monday mornings when the Snowflake warehouse is under peak load. Walk me through your diagnostic process and the specific changes you would make — in SQL, the data model, or Sigma itself — to fix it sustainably.

Describe a dimensional model you designed for a reporting layer on top of Snowflake, BigQuery, or Databricks. How did you structure facts and dimensions, how did you handle slowly changing dimensions, and how did you ensure business users got consistent metric definitions across different dashboards?

Tell me about a time a business stakeholder told you exactly what report they wanted — and you pushed back. What did they ask for, why was it wrong or insufficient, how did you redirect them, and did the report you actually built get used?
