It's the worst. I still can't do it. The point is that they want to make sure you understand consultative sales. Look that up. I would start with a question. i.e. "What do you like to do for fun or as a hobby?" followed with "How do you manage your time?" blah blah "Would you benefit from something that helps you keep track of your things you have to do?". Find out what is important to the client and tailor your conversation in that manner.
