It's important here to focus on theword "implemented." There's nothing wrong with having a thousand great ideas, but if the only place they live is on your notepad what's the point?Better still, you need a good ending. Ifyour previous company took youradvice and ended up going bankrupt,that's not such a great example either.Be prepared with a story about an ideaof yours that was taken from idea toimplementation, and consideredsuccessful.
