Every minute you’re looking for a job you’re under a spot light. It’s like you’re delivering a PowerPoint. Your presentation has to immediately explain what the benefit will be to them or their organization.
You need to start by describing the results first, and then tell them how you'll get them there. If you're just hoping the product will be a benefit for them once you explain its features, you haven't done your homework. And you’ll be road kill.
Understand this now - You don't need to impress them with your credentials... you need to communicate with them—and that means talking the way they talk, about the things they talk about. Their issues – their problems – THEN - your solution - you!
