"After identifying they fit the target market, here is how I would describe your Swiss army knife to someone who has never seen it before. 'It sounds to me like you could benefit from a single tool that can tackle multiple different tasks, and the best tool on the market right now is our Swiss army knife. Its multiple features include knife blades, levers, pliers, screwdrivers, a corkscrew, and even a toothpick. Each component can be used for several different purposes, which doubles the knife's usefulness. And perhaps the best feature of all is that the Swiss army knife's tools all fold into a compact unit that fits right in your pants pocket so you'll have it with you wherever you go and whenever you need it. I know Company A and Company B both offer pocket knives at a similar price point, but Company A doesn't offer as many tools and Company B's is too bulky to fit in a pocket. Trust me, this Swiss army knife is the best pocket knife available and it's the only tool you'll ever need.'"

Do your homework before the interview so you are prepared for this type of question. You should know as much as possible about the company's products, markets, and competitors. You will want to consider the target audience (market) when describing the product's features, and mentioning a competitor shows the depth of your knowledge.
