Technical Interview Preparation Guide
BI Developer interviews focus heavily on SQL proficiency and scenario-based dashboard design questions. You will likely be given a schema and asked to write SQL queries calculating metrics like month-over-month revenue growth, churn rate, or running totals. Be prepared to explain DAX context transition (row context vs filter context in Power BI), discuss Tableau LOD expressions, and explain how you optimize slow-loading dashboards.
Frequently Asked Questions
Which tool is more in demand: Power BI or Tableau?

What is the difference between a BI Developer and a Data Analyst?
Data Analysts focus on analyzing data to answer specific business questions; BI Developers focus on building the scalable reporting pipelines, data models, and automated dashboard platforms.
Is Python necessary for a BI Developer?
