Can you share details about the largest data set you’ve worked with? How many entries and variables did the data set comprise? What kind of data was included?

Working with large datasets and dealing with a substantial number of variables and columns is important for a lot of hiring managers. When answering the question, you don’t have to reveal background information about the project or how you managed each stage. Focus on the size and type of data.

Example Answer
“I believe the largest data set I’ve worked with was within a joint software development project. The data set comprised more than a million records and 600-700 variables. My team and I had to work with Marketing data which we later loaded into an analytical tool to perform EDA.”
