How to Ask for a Recommendation Letter After an Internship

Your internship ends in three weeks, your supervisor actually liked your work, and next spring you will be applying for graduate jobs or a master's programme that wants two references. Asking for a recommendation letter after an internship feels awkward, but it is far easier now, while your work is fresh in their mind, than in eight months when they are trying to remember which intern you were.

I have been on both sides of this. As an intern I waited too long and got a letter so generic it could have been about anyone. As a manager I have written dozens, and the strongest ones always came from interns who asked well. Here is what that looks like in practice.

When to Ask for a Recommendation Letter After an Internship

The best window is the last two to three weeks of your placement. Your manager has seen enough of your work to say something specific, and they have not yet moved on to the next cohort.

If you do not need the letter yet, ask for it anyway. You can frame it simply: "I'll be applying for graduate roles next year. Would you be willing to write a short letter now that I could use, or be a reference when the time comes?" Some managers will write it immediately and email you a signed PDF. Others will agree to be contacted later. Both are wins.

If your internship already ended, you can still ask. Within six months is usually fine. After a year, reintroduce yourself with a reminder of the project you worked on and the dates you were there.

Who Should Write It

The right person is the one who saw your work most closely, not the one with the most impressive job title. A detailed letter from your day-to-day supervisor beats a vague one from a department director who met you twice.

Your direct manager is the default choice. They assigned your work and saw the results.
A senior colleague or project lead works if you spent most of your time on their team.
A director or partner only makes sense if they genuinely supervised a piece of your work.

If you are applying to a specific field, think about who can speak to the relevant skills. An application for a data analyst role benefits more from the person who reviewed your SQL queries than from the person who signed your timesheets.

How to Ask, Word for Word

Ask in person or on a video call first if you can, then follow up in writing. A short conversation lets them say yes warmly, and the email gives them everything they need to actually write it.

In person, keep it to two sentences:

"I've really valued working on the client onboarding project with you. Would you be comfortable writing me a recommendation letter for graduate applications? I can send over some notes to make it easier."

Then send a follow-up email the same day that includes:

What the letter is for, such as graduate schemes in marketing or a specific master's course.
The deadline, giving them at least two to three weeks.
Three or four bullet points on what you worked on, with numbers where possible.
Any format requirements, for example on letterhead, addressed "To whom it may concern", or submitted through a portal.
Your CV attached.

Those bullet points matter more than anything else in the email. "Built a dashboard that cut the weekly reporting time from 3 hours to 40 minutes" gives your manager a concrete sentence to write. If you have been keeping notes of your wins throughout the internship, this is where they pay off. The same notes help with preparing for your first performance review later on.

Do Not Offer to Write It Yourself

A lot of career advice suggests you offer to draft the letter for your manager to "edit and sign". It sounds efficient. I would avoid it unless they ask you to.

Letters drafted by the candidate tend to read like it. They praise in a slightly off tone, use the same phrases you use in your cover letter, and miss the outsider's perspective that makes a reference credible. Recruiters and admissions tutors read hundreds of these and notice. Some managers are also uncomfortable being asked, and quietly read the offer as you not trusting them to do it well.

Give them strong raw material instead: the bullet points, a reminder of feedback they gave you, a sentence about what you hope to do next. That gets you a letter that sounds like them and still covers what you need. If your manager explicitly says, "Can you draft something and I'll adjust it?", then go ahead, but keep it factual and let them add the praise.

What a Strong Letter Includes

You will not control what goes in, but knowing what good looks like helps you prepare the right notes.

Element	Weak version	Strong version
Context	"Sam was an intern with us."	"Sam joined our 6-person analytics team for a 12-week summer internship."
Specific work	"Sam helped with reports."	"Sam rebuilt our weekly sales report, saving the team about 2 hours a week."
Qualities	"Hard-working and reliable."	"Asked sharp questions in client calls and followed up without being prompted."
Endorsement	"I recommend Sam."	"I would hire Sam again and recommend them without reservation."

If you worked remotely, mention specific moments when you communicated proactively, because remote managers often have less to draw on. Several of the habits in standing out in a remote internship double as material for this request.

After They Say Yes

Send a gentle reminder about five working days before the deadline if you have not heard back. Something short like "Just checking in on the letter for the 15th; happy to send anything else that helps" is enough. Managers are busy and most delays are forgetfulness, not reluctance.

Once it is done, send a proper thank-you. A handwritten card is memorable, but a sincere email works. Then follow up again when you get the place or the job. People who write references rarely hear how things turned out, and telling them builds a relationship you can call on again in five years.

Keep a copy of the letter and the writer's current contact details in the same place you track your internship applications, so you are not hunting for them under a deadline.

FAQ

How long before a deadline should I ask for a recommendation letter?

Give at least two to three weeks, and four if it is a busy period like year-end. Asking during the final weeks of your internship, months before you need it, is better still.

What if my manager says no or seems hesitant?

Thank them and do not push. A reluctant writer produces a lukewarm letter, which can hurt more than help. Ask another colleague who saw your work closely instead.

Is a LinkedIn recommendation the same as a recommendation letter?

No. A LinkedIn recommendation is public and short, and it is useful for your profile. Graduate schemes and universities usually want a formal letter or a direct reference, so ask for both if you can.

Can I use the same letter for several applications?

Yes, a general letter addressed "To whom it may concern" can be reused for similar roles. For a very specific application, such as a competitive master's programme, ask whether your manager would tailor a version.
