Innovation is the cornerstone of any successful company. If you show me a highly successful company, I will show you people within that company that were innovative thinkers. Great examples are Steve Jobs from Apple, Bill gates from Microsoft, and Jeff Bezos of Amazon just to name a few. The hiring manager is posing this as a two-part question to see if your response is clear, concise, and related to the question. Stay on point with your response, because that's what they're looking for. Think about this question for a minute to dissect what they are asking. They are a company of innovators.....which means, will you fit into their culture and be able to come up with ideas that will be innovative. They will be listening attentively to how you articulate your message about your breakthrough idea. Walk them through how you came up with the idea, what your thought process was, how you got approval to move forward, and how you executed on the idea.
