Part of the internship and job search process is gathering references or recommendations that showcase your knowledge, skills and abilities.
A reference is generally a person who is willing to speak to a potential employer about you over the phone or via email. Your references are compiled into a document that can be submitted at the time of application or during an interview.
A recommendation is generally a letter written by one of your references that you submit with your application or include in your portfolio.
You can also request that your references complete a recommendation on your LinkedIn account or endorse your skills and expertise on your profile.
