The dataset is private but the general gist is its like 100,000 rows with conversion and revenue data with time and 2 other dimensions. There are some outliers (clearly errors) in the data and strong seasonality differences in some dimensions, and data sparsity in others. The applicant isn't told about these, but we look for them to find it in their analysis and control for it in a predictive model they are asked to build based on the data.
