I recently interviewed at a SaaS company only to realize how I need to better organize my work to tell a story of progress.
Many of my examples failed because in most cases, I had the "after" or the "during" images. I was then in a position of talking through the "before" which of course is not as good as simply showing it. It struck me how uncompelling it was to show these things without any context & that's my lesson for the day.
UX, like acne products, is about a highly visible before & after.
