The case is designed to be presented to the candidate by an interviewer, who plays the role of someone who wants to set up a wine cellar in his basement.
I’m thinking about setting up a wine cellar in my basement. The way I see it, shelf space would be divided into two sections: (1) a “drinking” section where I store bottles for my own consumption and (2) an “investment” section where I store bottles that I intend to sell at a profit after they appreciate in value several years down the line. The idea is to earn enough money with the “investment” section of the cellar in order to subsidize whatever I consume in the “drinking” section over time.
I'm obviously constrained by several things: the amount of money I am able to spend, the amount of wine I can (or want to) drink, the space available for the cellar, and so on.
