Types of internship
Summer internships usually run for eight to twelve weeks between academic years and often act as an extended interview for a graduate job. Placement years, sometimes called a sandwich year, run for nine to twelve months as part of a degree. Insight programmes are shorter, typically a few days, and are aimed at first-year students.
Do internships have to be paid?
If you count as a worker, you are legally entitled to at least the National Minimum Wage. Interns doing real work with set hours and responsibilities almost always count. Genuine student placements required as part of a course, and short work shadowing, are the main exceptions.
If an advert asks you to work set hours for free, that is a warning sign. Ask the employer to explain the arrangement before you accept it.
Making an internship count
Agree what you will actually work on in the first week, keep a short record of what you deliver, and ask for feedback halfway through. That record becomes the evidence in your graduate applications.
Ask about return offers early. Many employers decide on graduate conversions before the internship ends.
