General Mills Associate Marketing Manager interview questions

You are a Marketing Manager for Brand X, and there is a shortage of a key ingredient just before a major key selling season. Do you: a) Send only the amount of product which you can produce with the ingredients you have on hand - which will mean shipping customers less product that they had ordered during a time of year where they rely on your products to drive business b) Substitute a different ingredient into the product, which from your understanding the consumer will not notice a difference, and complete all of the orders your customers have placed which will allow them to have a successful key season.

How do you market a product that's really healthy/has great benefits but tastes/smells/feels horrible?
