Re: Internship
Dear Hiring Manager,
TechStart Inc. builds software that solves everyday problems, and I want to spend my internship writing code that real people use. I am studying for a B.S. in Computer Science at the University of California, Berkeley, and I am applying for your internship to keep learning in a fast-moving startup team.
This summer, as a software development intern, I built three RESTful APIs in Python and Flask that reduced data retrieval time by 20%, and I worked with a team of five to add unit tests that brought our code coverage to 90%. Code review there taught me to write for the next reader, not just the compiler. I use Python, Java, SQL, Flask and Git every day, and I am comfortable picking up new tools quickly.
Before that, as a research assistant intern in a university lab, I optimized PostgreSQL queries to improve performance by 15%, cleaned and analyzed more than 10,000 records in Python, and helped design experiments that made our data collection 30% more efficient. That work showed me how much careful data handling matters before any analysis begins. I also led a student team that built a mobile study-planning app, which improved productivity by 20% in beta testing.
I would be thrilled to talk about the projects TechStart's interns contribute to. Thank you for considering my application.
Sincerely,
Alex Johnson
What Other employers look for
These roles span students, interns, career changers, and generalists, so screening focuses on transferable evidence and whether your direction is coherent.
Writing a stronger Internship cover letter
01
Explain the change directly
A career change without explanation invites the reader to guess. Two honest sentences about why you are moving remove the question.
02
Address the experience gap head on
Name the gap and what you have done to close it. Ignoring it is more damaging than the gap itself.
Mistakes to avoid
- Listing unrelated jobs chronologically so the relevant evidence is buried
- Claiming transferable skills without a concrete example behind them
- Leaving the career change unexplained, which makes the reader construct their own story
Internship cover letter questions
What should an Internship cover letter include?
Written for an Internship opening at TechStart Inc., this sample treats every sentence like it will be audited, because talent acquisition probably will. Make sure the first line names the role, the middle proves you have shipped other outcomes, and the last line asks for a next step rather than wishing luck. The draft holds all of that in 4 paragraphs without crowding the page.
How long should an Internship cover letter be?
221 words is the working target here, tuned until talent acquisition could absorb it in under a minute. White space persuades too: short other paragraphs like these get read to the end, dense ones get skimmed and forgotten. Stop at the paragraph count this sample uses (4); beyond that, letters read as a resume retold aloud.
How do I tailor this Internship cover letter to a specific job?
Treat this draft as scaffolding around your own record: keep the structure that convinced talent acquisition to keep reading, then re-point every detail at the new vacancy. Rework the middle so the achievement this version spends on other wins speaks instead to the new posting's first listed responsibility. Five focused minutes of that editing beats an hour spent rewriting from scratch.
