In your portfolio should be your resume, a letter of reference, samples of diagrams or events you have worked on in your previous positions or schooling, performance monitoring documents if you have them, school transcripts and certificates showing your grades, and some samples of your skills like writing documents or events that you may have planned within your career.
The most essential reason it is important is in its ability to allow the interviewer a better way to review your growth and development and compare it to how you may grow in their company. Another important feature in a portfolio is the fact that it is or should be constantly changing. As an interviewee, your portfolio from 2008 should not have the same accomplishments as 2011 seeing as though you have had 3 years of opportunity to gain new skills, experienced different situations, and overall accomplished harder and or different challenges. Since most people don’t use portfolios, having one can set you apart from other applicants when applying to a position. With a portfolio you are able to customize your style of portfolio and showcase not only your jobs skills and experience, but also your ability to be creative. How you choose to organize your portfolio advertises your personality to potential employers and organizations and that alone may get you the job.
