Duolingo Internship 2027–2028: Programs, Deadlines & How to Apply

Quick Facts

Last updated: October 2026

Duolingo receives thousands of internship applications each year for roughly 25 Thrive seats and a small number of Standard slots, making it one of the most selective consumer-tech internship programs in the country. For the 2027–2028 cycle, you apply September to November 2026, you intern summer 2027. Unlike most tech companies, Duolingo does not review applications on a rolling basis, so missing the posted deadline means waiting a full year. By October 11, 2026 that already applied to three postings: both software engineering tracks, whose September 30 deadline has passed, and the Associate Product Manager posting, which closed on its October 7 deadline. On October 11, 2026 the one intern posting listed on careers.duolingo.com was Illustrator, Intern (Detroit, MI), with a November 5, 2026 application deadline, and no Data Science or Product Design intern posting was listed.

What Is a Duolingo Internship?

A Duolingo internship is a paid, full-time, 10- to 12-week placement that puts students on real product and engineering teams building the world's most popular language-learning app, used by over 100 million monthly active learners. The program splits into two tracks. The Standard track hires juniors for Software Engineering, Data Science, and Associate Product Manager roles. The Thrive track, launched in 2021, is a dedicated pipeline for sophomores from underrepresented communities in tech, covering SWE, Product Design, and Studio Art. Thrive interns go through a two-week onboarding called Hootcamp, work on group projects mentored by senior hosts, and receive both a Thrive Host and a Thrive Buddy mentor. Across both tracks, the conversion rate is 76%, meaning more than three in four interns receive return offers.

When Do Duolingo Internship Applications Open for 2027–2028?

Duolingo's internship calendar follows a tight, hard-deadline pattern that repeats each fall. For the Summer 2026 cycle, Standard SWE applications opened in early September 2025, Thrive SWE closed September 29, APM and Data Science deadlines landed on October 1, and Product Design and Studio Art Thrive postings appeared in early November. Interviews ran October through January, and offers landed November through February. Expect the summer 2027 cycle to follow the same rhythm, shifted forward by one year. The key insight: these are not rolling deadlines, so applying on time is not optional.

How to read this page: our dates come from tracking previous recruiting cycles and daily posting data. Treat them as informed estimates based on historical patterns, not confirmed dates. The company's official careers page is always the most current source. If a role is posted there, go by that, even if this page suggests the window hasn't opened yet.

Why You Must Apply the Week Applications Open

Duolingo does not use rolling admissions, which makes the hard-deadline structure both simpler and less forgiving than most tech internships. When a deadline passes, the door closes for a full year. For the Summer 2026 cycle, Thrive SWE closed September 29 and APM closed October 1. That is a window of weeks, not months. The implication: your resume, projects, and interview prep need to be ready before September, not after. A recruiter tip from Duolingo's own university recruiting team: apply when you meet 70% or more of the qualifications and do not self-disqualify. Roughly 58 of every 100 applicants do not meet stated requirements, so the bar for applying is lower than most candidates assume.

Which Duolingo Internship Programs Should You Target?

Duolingo runs its internships through two tracks: the Standard program for juniors and the Thrive program for sophomores from underrepresented communities in tech. Which track fits you depends on your year in school and background. Both lead to the same 76% return-offer pipeline.

See every open role on the Duolingo careers portal. Duolingo is heavily invested in AI-powered language learning, so engineering roles that touch ML, A/B testing, and personalization may carry more weight than in prior cycles.

What Are the Eligibility Requirements?

Duolingo's eligibility splits cleanly by track, and the year-in-school requirement is strict:

• Standard track enrollment: actively enrolled in an accredited Bachelor's or Master's program as a junior. Graduating Fall 2027 through Spring 2028 for summer 2027 roles (projected from Summer 2026 cycle, which targeted Fall 2026 through Spring 2027).

• Thrive track enrollment: second-year undergraduate from an underrepresented community in tech. Graduating Fall 2028 through Spring 2029 for summer 2027 roles (projected). The Thrive program launched in 2021 and accepts approximately 25 students per cohort.

• Technical prerequisites (SWE): at least two college computer science courses completed and programming experience in Java, Python, Kotlin, or Swift. Product Design requires a portfolio with one to two independently driven projects and Figma or Adobe XD experience.

• Work authorization: CPT supported for F-1 students, OPT for post-graduation. H-1B and TN visa sponsorship available for full-time conversion. Duolingo sponsored 59 visas in a recent year.

Does Duolingo Have a GPA Cutoff?

Duolingo does not publish a hard GPA minimum. The emphasis in their interview process falls on coding ability, product thinking, and data-driven decision-making rather than a transcript number. Their official recruiter advice: apply when you meet 70% or more of qualifications. Strong projects, a clean coding assessment, and evidence of A/B testing or experimentation mindset carry more weight than a decimal on your GPA.

What Skills Does Duolingo Look For, and How Do You Build Them?

Read across six Duolingo intern job descriptions, three SWE variants (Standard and Thrive), one Data Science, one APM, and one Product Design, and the pattern is clear. Programming appears in five of six, data-driven decision-making in four, and A/B testing or experimentation in three. But the skill list only tells half the story. Duolingo obsessively experiments on everything from lesson flows to the owl's facial expressions, so the interview process rewards candidates who can measure the impact of what they build, not just build it.

And every skill in that chart maps to a remote Externship where you finish a real project before a role opens.

How close is the overlap? The BeReal project is product-management work that yields the feature-scoping and user-research evidence Duolingo's APM interviews probe for, and the Wayfair project ends on the engineering story a pair-programming round wants.

What Is the Duolingo Application and Interview Process Like?

Duolingo's engineering interview funnel runs three stages plus a multi-session virtual onsite. The total timeline is 4 to 6 weeks from application to offer:

1. Apply on careers.duolingo.com. Filter by Intern or Thrive, pick your specific track, and submit before the hard deadline. No late applications are accepted.

2. Online coding assessment (60 minutes). An asynchronous, auto-graded algorithmic assessment on CodeSignal. Four questions, heavy on graph traversal and medium-difficulty problems. Supports Python, Java, or JavaScript. Apply early: the OA invitation typically follows within 1 to 2 weeks of submission.

3. Technical video interview (60 minutes). Live coding on CodeSignal with a Duolingo engineer (plus one shadowing). Two problems testing real engineering sense and product thinking, not just algorithmic speed. Kotlin and Swift also supported here.

4. Virtual onsite (half-day, 4 sessions). Pair Programming (75 min): work on production-like code in VS Code Live Share. Code Review (60 min): identify issues and suggest improvements to existing code, specialized by platform (Backend, iOS, Android). Whiteboard (60 min): algorithmic problem-solving emphasizing analytical thinking and communication. Coffee Chat: informal fit conversation with a team member.

5. Design interview (60 minutes, backend/mobile roles only). High-level architecture discussion with no single correct answer. Evaluates your problem-solving approach and system-design thinking.

6. Offer decision. Typically within 1 to 2 weeks of the final onsite round. The 86% offer-acceptance rate suggests competitive terms.

So the three skills to drill are clear: algorithmic fluency for the OA and whiteboard (Glassdoor rates difficulty at 3.17 out of 5, with a 47% positive interview experience), comfort working in someone else's codebase for pair programming and code review, and product-thinking stories that show you care about measuring impact. Duolingo does not focus on hard LeetCode puzzles but tests real engineering sense deeply.

How Do You Stand Out at a Company That Gets Thousands of Applications?

Three moves, all before September. First, meet the deadline with margin: Duolingo does not do rolling review, so being ready when applications open in September is the entire timing strategy. Second, prepare for the pair-programming and code-review rounds specifically, not just LeetCode. Duolingo tests whether you can work in someone else's codebase and think about code quality, which is a different muscle than competitive programming. Drill by reviewing open-source pull requests and pair-programming with a friend in VS Code Live Share. Third, bring product-thinking stories backed by data. Duolingo's culture is obsessively experimental: they A/B test everything. So when they ask you to describe a project, the answer should include what you measured and what the result was, not just what you built. And remember: 76% of interns get return offers, so the internship itself is effectively a 10-week interview for a full-time seat at a company where new-grad SWE compensation starts at $123,000 to $167,000.

FAQ

When do Duolingo internship applications open for summer 2027?

They already did. Standard SWE, Thrive SWE and APM postings for summer 2027 went live on careers.duolingo.com on September 15–16, 2026. The two SWE reqs closed on September 30, 2026 and APM closed on October 7, 2026 (deadlines printed in the postings). On October 11, 2026 the one intern posting listed was Illustrator, Intern (Detroit, MI), posted October 5, 2026 with an application deadline of November 5, 2026. No Data Science or Product Design intern posting was listed that day; the early October to early November estimate for those came from the Summer 2026 cycle.

Is Duolingo internship hiring rolling?

No. Duolingo uses hard deadlines for every track. Once the posted deadline passes, the application closes and no late submissions are accepted. This makes Duolingo unusual among large tech companies, where rolling review is the norm.

How much does a Duolingo internship pay?

Self-reported Summer 2025 figures on Levels.fyi put Standard interns at $50 to $52 per hour and Thrive interns at $43 to $45 per hour. Both tracks include a $1,000 per month housing stipend, daily catered meals from in-house chefs, and relocation support. Levels.fyi reports $52 per hour for SWE interns. The one intern posting listed on October 11, 2026, Illustrator, Intern (Detroit, MI), prints an hourly range of $39 to $41.

What is the difference between the Standard and Thrive programs?

Standard targets juniors for SWE, Data Science, and APM at $50 to $52 per hour. Thrive targets sophomores from underrepresented communities for SWE, Product Design, and Studio Art at $43 to $45 per hour, with added mentorship through Hootcamp, group projects, senior hosts, and Thrive Buddies.

What is the Duolingo internship interview process like?

For engineering: a 60-minute CodeSignal OA, a 60-minute live technical interview, then a virtual onsite with pair programming (75 min), code review (60 min), whiteboard (60 min), and a coffee chat. APM replaces coding with a take-home feature proposal and two 45-minute product interviews.

Does Duolingo sponsor visas for interns?

Yes. CPT is supported for F-1 students during the internship, and OPT is available post-graduation. For full-time conversion, Duolingo sponsors H-1B and TN visas. The company sponsored 59 visas in a recent year across engineering, AI, and data roles.

Do Duolingo interns get return offers?

Yes. The conversion rate across both Standard and Thrive tracks is 76%, with an 86% offer-acceptance rate. New-grad SWE total compensation starts at $123,300 to $166,800 per year at the Pittsburgh headquarters.

Is the Duolingo internship remote or in-person?

In-person at the Pittsburgh headquarters in East Liberty, with a 4-day in-office policy (Monday through Thursday) and Friday flex. Data Science interns may also be placed in the New York office. Duolingo does not offer remote internships.

Duolingo's deadline-driven process means the work you do before September decides everything. A remote Externship turns 'interested in Duolingo' into a finished project with real product-thinking and technical evidence that a fall application can point at.
