  • User training
Good Answer Example:

I have extensive experience working with Tableau and Power BI to create dashboards that visualize complex data for stakeholders. For example, at my last job, I developed a dashboard that tracked sales metrics across regions, which helped our team identify a 15% increase in sales opportunities in underperforming territories. I also trained team members on using these tools, enhancing their analytics skills.

Bad Answer Example:

I have used several BI tools, but I prefer not to go into details.

Red Flags:

Good Answer Example:

To ensure data accuracy, I implement a combination of manual checks and automated scripts that run daily validation processes. For instance, I cross-verify key performance data with the original source databases. If I notice discrepancies, I collaborate with the data engineering team to quickly identify the source of the error. I’ve implemented regular data audits that reduced our data errors by 25% over the last year.

Bad Answer Example:

I generally trust that the data comes in correctly, and I don’t worry much about it.
