I’ve been out of school for six years and only about 4 products that I’ve designed actually made it to market. I worked in startups for half that time and consultancies for the other half. You cannot show a lot of work because it’s under NDA, so that’s why the “re-do” projects come out. While I don’t have any re-done student projects, I do have a lot of re-done personal projects on my portfolio that are loosely based on my professional work that is under NDA.
