Portfolios allow you to exhibit your talents, experience, and abilities in a more detailed manner than a typical resume. Online portfolios are a more modern twist than conventional portfolios, and you may include a link to your online portfolio in your resumes, cover letters, email signatures, and LinkedIn profiles.
A portfolio may be useful in a job hunt for numerous reasons:
To exhibit examples of your work (writing, design, etc.)
To give detailed case studies or project descriptions pertaining to your job.
To display measurable data in the form of a graph or chart.
To incorporate multimedia elements into your job hunts, such as movies or infographics.
