When I interview I prefer to see a printed portfolio, but bound together in some way that it can all be taken apart so that I can get an overall view of projects. Can’t do that with an electronic presentations one after another. This gives me a feel for the designers methodology, style and content, not just the flash of the presentation. Flash is important and does engage, but there must be real design content.
Print it, organize it and for the most part let it sell itself.
