Internship Program

How an internship program works

Most corporate programs follow the academic calendar. Recruiting for summer interns typically starts in the fall, often through campus recruitment at target schools, career fairs and online applications, with offers going out between October and February. Interns start in May or June, work for 10 to 12 weeks, and the strongest receive return offers for a full-time role after graduation.

A program is more than a set of summer jobs. It has a defined cohort, a start date, a manager and a project for every intern, a shared training track, and an evaluation at the end that feeds the return-offer decision.

Paid vs unpaid internships

In the US, whether an intern must be paid depends on the FLSA. For for-profit employers, the Department of Labor applies the "primary beneficiary test": an unpaid internship is only lawful if the intern, not the employer, is the main beneficiary. Factors include whether the internship is tied to formal education or academic credit, whether it follows the academic calendar, and whether the intern displaces paid employees. An intern who does productive work a paid employee would otherwise do generally has to be paid at least minimum wage and overtime.

In practice, most employers simply pay interns. Paid programs attract a wider and more diverse candidate pool, since many students can't afford to work for free, and they remove the legal question. Several states have their own rules, and rules differ outside the US.

Running intern hiring at volume

An employer hiring 200 interns across 15 locations is running a high-volume campaign with a hard deadline. What works:

• Fixed hiring windows with a single application, screening and interview process for every location
• Structured interviews and short skills assessments rather than GPA cutoffs, which narrow the pool without predicting much
• A clear offer deadline that's reasonable for students (two to three weeks is common)
• Pre-start contact between offer and start to keep reneges down

Once interns arrive, treat their first week like any employee onboarding: accounts ready on day one, a named buddy, and a project scoped before they start.

Common mistakes

• No real project. Interns who spend the summer on filing don't accept return offers.
• Managers who didn't ask for an intern. Assign interns only to managers who will mentor them.
• Return offers made too late. Students with competing offers decide in early fall.
• Measuring headcount instead of conversion. A program that hires 100 interns and converts 10 is an expensive summer camp.
• Unpaid roles that fail the primary beneficiary test.
