Based on my experience they always use one case - they show numbers and subcategories featured in the "event" (how they call category that is being promoted, i.e. has discounts). The numbers show KPI's such as number of visits, conversion rate, revenue and average purchase order. Your task would be to explain if there are any trends and if you can explain why that is the case. Then they will show more details about the category, comparing two months and how certain furniture was featured and ask you how would you do the selection for the next month.
