Sample answer
“In my internship at a local non-profit, I worked on analyzing donor data to identify trends. I used Excel for data cleaning and SQL to extract relevant information from our database. The biggest challenge was dealing with missing values, which I addressed by implementing a statistical method to estimate them. My analysis revealed that 60% of our donations came from repeat donors, which led to a targeted campaign increasing engagement by 30%.”
