Sample answer
“During my internship at a retail company, I was given a large dataset of customer purchase history. I used SQL to query the data and Power BI to visualize it. I discovered that our sales peaked during specific holidays, leading to a 20% increase in targeted marketing efforts during those times. Despite facing challenges with data cleanliness, I implemented a data validation process that improved accuracy. This experience taught me the importance of thorough data preparation.”
