Last summer, about 1.2 million college students showed up on day one of an internship and had the same thought: what am I supposed to be doing here?
That's the gap between the career-center definition of an internship ("a structured work experience that integrates classroom learning with professional development") and the version you actually need. The structured version is fine for a syllabus. But it doesn't tell you whether you'll be writing code that ships to users or fetching oat milk for a VP who won't learn your name. It doesn't tell you whether an unpaid offer is even legal. And it doesn't tell you whether skipping an internship altogether will tank your chances at a real job.
So here's the version we'd want if we were applying right now. What an internship job actually involves, what it pays, whether the unpaid ones are even legal, and whether you need one at all.
Quick Takeaways
- An internship is temporary, supervised work experience, typically 8–12 weeks
- 63.1% of interns got full-time offers in 2024–25, the highest rate in five years (NACE)
- Unpaid internships at for-profit companies must pass a 7-factor federal test to be legal
- Average US intern pay is $23.04/hour, but ranges from $0 to $72/hour by industry
- In finance and consulting, internships are basically required. In creative fields, your portfolio matters more
What is an internship, exactly?
It's a short-term work placement — usually one summer or one semester, where a company lets you try the job, and both sides decide whether it's a fit. That's the part most definitions leave out: it's a two-way audition, not a favor.
The National Association of Colleges and Employers (NACE) sets the standard most US employers follow. Their formal definition emphasizes "experiential learning" and "practical application," but the internship meaning is simpler than the language suggests. You get a supervisor. You get scoped projects. You work alongside a team but at a junior level. And the whole thing has an end date.
That end date is what separates an internship from a part-time job. Your barista shifts are transactional: hours for wages. An internship is a probationary on-ramp. Companies invest in training you because they're hoping to hire you afterward, and the numbers back that up: NACE's 2025 data shows 63.1% of interns received full-time return offers last cycle. That's the highest conversion rate in five years, and 88.3% of those who got offers accepted them.
It's cheaper for a company to develop a known intern into a hire than to gamble on a stranger from the applicant pile. That's the business case for internships, and knowing it changes how you approach yours.
What is the difference between an internship and an externship, apprenticeship, or co-op?
They're all work-based learning, but they differ on duration, pay, and what you walk away with. Externships are job shadowing. Co-ops are internships' longer, more serious cousin. Apprenticeships are a multi-year commitment that ends with a credential.
Here's the quick breakdown:
An externship runs anywhere from a single day to about eight weeks. You observe. You shadow. You don't really do the work. You watch someone else do it. They're most common in healthcare and law, where "extern" has a specific clinical meaning.
A co-op (cooperative education) alternates full-time work terms with school terms, usually lasting three to six months per rotation. They're almost always paid and carry academic credit. Schools like Northeastern and Drexel built their reputations on the model. If an internship is a test drive, a co-op is a lease.
An apprenticeship is a DOL-registered program that combines paid work with at least 144 classroom hours per year and lasts one to six years. You earn a nationally recognized credential at the end. There are roughly 680,000 active registered apprentices in the US today, and the model has expanded well beyond construction into cybersecurity, IT, and healthcare.
Two newer categories get confused constantly. Micro-internships (the term Parker Dewey coined) are paid, short-form project gigs: 5 to 40 hours, often remote, $15–$25/hour. They're real work. Forage job simulations are free, self-paced practice modules from companies like JPMorgan and BCG. They're useful for exploring careers, but they're training exercises, not paid positions.
Are unpaid internships legal?
At for-profit companies, only if the intern is the "primary beneficiary" of the arrangement — not the employer. That's the rule from the Department of Labor's Fact Sheet #71, and it's decided by a seven-factor test.
The seven factors boil down to a few key questions.
Did both sides understand there'd be no pay?
Does the work look more like training than like an entry-level job?
Is it tied to your formal education?
And the factor that breaks most exploitative setups: does your work replace what a paid employee would otherwise do?
That last factor is how the landmark Glatt v. Fox Searchlight case went down. Production assistants on Black Swan were doing work that paid PAs would normally handle. The court agreed they should've been paid.
Quick rule of thumb: nonprofits and government agencies can use unpaid interns under the FLSA's volunteer exemption. For-profit companies can't unless all seven factors tilt toward the intern. If a startup is offering you an unpaid role that sounds suspiciously like their open marketing coordinator position, that's a flag.
The compensation question matters beyond legality, too. NACE's data consistently shows paid interns receive more job offers and higher starting salaries than both unpaid interns and students who didn't intern at all. The average paid intern earns $23.04/hour. At the high end, Google SWE interns make about $72/hour. At the other end, 43% of internships still pay nothing.
What do interns actually do all day?
It depends entirely on the industry, and the gap between the best and worst programs is enormous. At structured companies, you ship real work. At unstructured ones, you sort mail.
A software engineering intern at a major tech company owns a scoped feature for 12 weeks. You write production code, attend standups, do code reviews with your mentor, and present your project at the end of the summer. Hours run 40–50 per week. Pay at FAANG companies: $8,800–$13,700/month, often with a housing stipend on top.
An investment banking summer analyst lives in PowerPoint and Excel. You build pitchbooks, spread comps using FactSet, and format slides per a VP's redlines, often past midnight. Modeling (the work people picture when they think "banking") comes later, once the team trusts you. Hours: 80–100 per week. The 10-week summer annualizes to roughly $110K.
A marketing or PR intern at a mid-sized agency writes blog posts that go out under client bylines, builds media lists, schedules social posts, and pitches journalists. You're producing published work within your first month. Pay ranges from unpaid at small agencies to $20–$30/hour at corporate in-house teams.
A Capitol Hill intern answers constituent calls, leads Capitol tours, sorts mail, and writes short hearing memos. House internships are now paid (roughly $15–$20/hour equivalent). Most nonprofit and think-tank Hill-adjacent programs are still unpaid.
The pattern is consistent: the "fetch coffee" stereotype lives in small, unstructured programs. Large employers with formal intern pipelines give you real work because they're using the summer to evaluate whether to hire you.
How long do internships last — and when should you apply?
Most run 8–12 weeks in summer, but application timelines vary wildly. Finance opens 12–18 months early. Most other fields recruit 3–6 months out.
That timeline difference catches people off guard. If you want a Goldman Sachs summer analyst seat for 2027, you're applying during sophomore fall of 2026. If you want a marketing internship at a mid-sized company, January through April of the same year is typical.
The market has gotten tighter. Handshake's Internships Index 2025 found internship postings fell more than 15% between January 2023 and January 2025, while student applications surged. Tech postings dropped about 30%. Translation: fewer openings, more applicants, and speed matters more than it used to.
Getting your applications out early and efficiently is a real competitive edge.
Do you actually need an internship to get a job?
In some fields, yes. In others, your portfolio, projects, or credentials matter more. The data says internships help a lot, but they're not the only path.
The salary gap is hard to ignore. NACE's Early Career Talent Survey found graduates with internship experience earned an average of $59,059 in their first job versus $44,048 for those without, a 34% difference. There's some selection bias in that number (students who land internships tend to be more employable to begin with), but the gap is consistent across years and industries.
Where it's basically required: investment banking, management consulting, and big tech all fill the majority of their entry-level seats from their intern conversion pipelines. Where it matters less: design, illustration, and editorial care more about your Behance or Substack than your resume line. Trades care about certifications and apprenticeship hours. Startups care about whether you can ship.
If a traditional internship isn't accessible (bad timing, family obligations, no connections at target companies), alternatives carry more weight than they used to. Outreachy pays a $7,000 stipend for a three-month open-source project and prioritizes underrepresented groups.
Parker Dewey micro-internships offer paid project work year-round. Google Summer of Code and MLH Fellowship function as quasi-internships for developers. And NACE's 2026 Job Outlook found 70% of employers now use skills-based hiring, up from 65% the prior year, with roughly half saying they have positions that are flexible on degree requirements.
The internship is still the single most valuable credential for most new grads. But it's no longer the only one employers accept.
The bottom line
An internship is supervised, temporary work designed primarily for students and recent grads, where both you and the company figure out whether there's a fit. The best ones pay well, give you real projects, and convert to full-time offers at high rates. The worst ones are illegal more often than students realize.
Know what type of opportunity you're being offered. Know what the legal floor is. Know what your alternatives look like in your specific field. And when you're ready to start applying, don't let the grind be the thing that stops you.
