An internship is a job training. Internships for professional careers are similar in some ways but not as rigorous as apprenticeships for professions, trade and vocational jobs, but the lack of standardisation and oversight leaves the term open to broad interpretation. Interns may be college or university students, high school students, or post-graduate adults. These positions may be paid or unpaid and are usually temporary.
In September 2008, Waag made a video for the City of Amsterdam about a possible future integrated transport system, called the Personal Travel Assistant.
