How to Write an Internship Job Description (With a Copy-Paste Template)
By The Internhuddle Team · Hiring · Published · 7 min read
Most internship postings are cut-down versions of a job ad: a vague title, a bullet list of demands, and no mention of what the intern will actually do. Strong students skim dozens of these a day — and apply to the ones that read like a plan, not a wish.
Quick answer: a great internship job description names the real project, the named mentorship arrangement, the pay and dates, and the selection process — in 300–600 words, with minimal requirements and encouraging "you might be a fit if" framing.
The eight sections that matter
- Title, in plain language. "Marketing Intern (Paid, Summer 2027)" beats "Growth Ninja Internship Opportunity". Include "paid" in the title — it measurably lifts click-through.
- The project. Two or three sentences on what they will actually build, run or research. This single section does more filtering and attracting than everything else combined.
- The mentorship arrangement. "You'll work with a dedicated mentor, with a weekly feedback session" tells candidates you have a plan for them. It is also a commitment device for you.
- Pay, dates, hours. State all three. Vague compensation and "flexible" dates read as disorganisation to exactly the candidates you want.
- What you'll learn. Interns choose internships to grow. Name the skills and tools they will leave with — it is the section they screenshot and compare.
- Who should apply. Two or three genuine must-haves, then "you might be a great fit if…" with encouraging signals (built something, ran something, curious about X). Long requirement lists cost you good applicants, not bad ones.
- The process. "Short application + 60-second video intro, then one 30-minute conversation, decision within two weeks." Naming the process (and its speed) is rare enough to be a differentiator.
- About you, briefly. Three sentences on the company at the end — not the beginning. Candidates care about their summer before your Series A.

You might be a great fit if: you've built, organised or created something you're proud of (coursework counts); you're curious about [domain]; and you like getting feedback. You do not need professional experience — that's what the internship is for.

Mistakes that quietly kill applications
- "Previous internship experience preferred" — for an internship. Delete it.
- No pay listed. The strongest candidates filter on it; several jurisdictions now require it.
- Ten-bullet requirement lists. Each bullet past three deters more good applicants than bad ones.
- Company-first structure. Four paragraphs of history before mentioning the role loses phone readers at paragraph two.
- No process description. Silence about what happens after "Apply" reads as a black hole — because it usually is one.
Frequently asked questions
What should an internship job description include?
Eight things: a plain-language title, the actual project the intern will work on, the mentorship arrangement, pay, dates and hours, location or remote setup, what they will learn, who should apply (in encouraging terms), and how the selection process works. Postings that name a real project and a real mentor consistently out-perform generic ones.
Should you list requirements in an internship posting?
Keep requirements minimal and honest — interns by definition lack experience. Replace long requirement lists with 'you might be a fit if…' framing, since research consistently shows that demanding requirement lists disproportionately deter qualified applicants from underrepresented groups. Two or three genuine must-haves is plenty.
Should internship postings include salary?
Yes. Postings with visible pay attract significantly more applications, and pay transparency is now legally required in a growing number of jurisdictions. Hiding compensation filters out precisely the candidates with the most options.
How long should an internship job description be?
300–600 words. Long enough to describe the real project, the mentor and the process; short enough to be read on a phone. Cut culture boilerplate before cutting substance.
