1. What internship recruiters want

They look for motivation, coherence and availability for the right dates.

Your goal: prove you understand the mission and can contribute, even as a beginner.

2. 3-paragraph structure (template)

Paragraph 1: short hook + why this internship and company.

Paragraph 2: one concrete proof (project, course, outcome) + result.

Paragraph 3: availability, dates, schedule and a clear ask.

Quick template: "Student in X, I am applying for Y. I delivered Z with this result. I am available from DATE to DATE and would love to discuss."

3. Prove value without experience

Use school projects, associations, competitions or side projects.

A project beats a list of courses when it shows a result.

  • Project with a clear goal
  • Tools or technologies used
  • Result or learning

4. Personalize with the job post

Take 3 to 5 keywords from the role and integrate them in your proof points.

Show you understand the mission and priorities.

  • Technical keywords
  • Core mission
  • Team or context

5. Final checklist

Re-read and ask: could I send this to any company?

  • 200 to 250 words
  • Company and role name
  • One strong proof point
  • Clean spelling
