Don’t forget to check your University’s career center. Also, call or visit the websites’ of local companies or government agencies in your city/state; these entities will likely not post on large national websites. In addition, network: ask your family and friends to email their family and friends about internship opportunities for you; include your resume.

Most importantly, don’t forget to rate your internship!
