In my previous role, I frequently used Power BI to analyze sales data trends for a consumer product line. I started by importing data from our CRM and utilizing Power Query to clean the data. I then created several interactive dashboards that visualized key metrics such as sales growth, customer acquisition costs, and product performance.
