I put together a document for an interview with Jet.com a couple of months ago. I thought it was a good example of my ability in slide creation and a good way to store a few of the projects I have worked on and how I might use them if moving jobs.
Unfortunately, I turned down the final interview. Loved the company, the environment, and the people, I just did not want to move from my position at the time. I still even use their site.
