Some important tips:
Watch your fonts. They may not make you, but they can easily break you. Be consistent with your story, and nothing too flashy.No "cool" pictures of yourself: This isn't Facebook so please don't show us the unique designer pose. It's most likely already been done and it tends to look silly.
Tell a story: From beginning to end show us who you are and what gets you going. Even if your projects are all over the place, show consistency in how each project is explained and what was tough, fun, sad, ugly or heartwarming about each of them. It may not get read but there is gold in repetition.
Have fun: As I have said in the past, you must have fun. This is what we do and, yes, it's fun. So relax a little, step away from the computer and do some portfolio research at Seven 11, or Target who cares just take yourself out of your element and look at things differently.
Make it available: Whether PDF, Website, or Coroflot make sure we can find your work. In today's economic grandeur, everyone is overworked and trying to save time. HR tends to get help from the creators of the corporate career site gods. These sites can throw you off your game by asking you for things you don't have and not asking for the things you do. If the situation comes up where you cannot upload the awesome images you have onto the corporate career site, then make sure you have a link to something on your resume. Most of the time a link to a PDF portfolio is ideal, however sometimes they are blocked and we have to rely on whatever we can find of Coroflot. So whatever you put online should be consistent with everything else you show, because you never know.
Keep at it and Good luck!!
