So now you have to present your portfolio and land that job. Do it in a way that is confident, but not cocky. Show that your work is your work by readily and thoroughly answer any questions the viewer may have.  Talk about why you did certain things, what you enjoyed about each project, whether or not you want to explore more areas similar to that project.  Dress well and talk clearly.  Don’t take forever, be brief—so make your sentences rich with information.
