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

Last updated: July 2026

Klarna processes over 3.4 million transactions per day, serving 118 million active consumers across 26 countries through partnerships with brands like H&M, Sephora, IKEA, and Nike. For the 2027–2028 cycle, the primary entry point is the 12-month Engineering Graduate Program, which opens applications in Q1 2027 for a fall 2027 start, while ad-hoc summer internships may appear on the Deel job board starting fall 2026. Klarna's AI-first hiring philosophy means candidates who can demonstrate practical experience with tools like GitHub Copilot and Cursor hold a measurable edge in the interview loop.

Quick Facts

Klarna's main early-career pipeline is a 12-month Engineering Graduate Program with a permanent contract from day one, not a traditional summer internship. Ad-hoc summer roles appear intermittently. The interview spans 5 to 6 rounds including a logic test and an AI-competency behavioral round unique to Klarna.

Externships are short, remote projects where you finish real work for a real company. The Wayfair AI Agent Engineering Externship and Beats by Dre Data Analytics Externship build the coding, data, and AI-tool evidence a Klarna application and its AI-first interview round reward.

What Is a Klarna Internship?

A Klarna internship puts early-career engineers inside one of the world's largest buy-now-pay-later platforms, processing over 3.4 million transactions daily for 118 million consumers and 966,000 merchants across 26 countries. The primary entry point is the 12-month Engineering Graduate Program based in Stockholm, which includes structured training in data, security, and software engineering, a 3-month team rotation across Klarna's small Agile squads, and a permanent full-time contract from day one. Ad-hoc summer internship positions also appear sporadically. Klarna's engineering culture is distinctly AI-first: the company has reduced headcount from 7,000 to roughly 3,400 through AI-driven efficiency, and interview panels now evaluate candidates on their practical use of tools like GitHub Copilot and Cursor. Following Klarna's September 2025 NYSE IPO (ticker: KLAR) and its July 2026 push for a US bank charter, the company is expanding beyond BNPL into broader consumer banking, creating new engineering surfaces for early-career contributors.

When Do Klarna Internship Applications Open for 2027–2028?

Klarna's early-career recruiting follows two tracks with different calendars. The 12-month Engineering Graduate Program historically opens applications in Q1 (roughly February through April) for a fall start in September or October. Ad-hoc summer internship postings, when available, tend to appear on the Deel job board between fall and winter of the prior year. For the Summer 2027 cycle, expect ad-hoc postings starting around Fall 2026, and Graduate Program applications opening in early 2027. Glassdoor data shows an average hiring timeline of 36 days for general roles and up to 62 days for Graduate Program candidates, so submitting early in the window is critical.

Why You Must Apply the Week Applications Open

Klarna does not publish a fixed deadline for its ad-hoc summer internships, and the Graduate Program application window is relatively narrow (roughly February through April). The practical implication: the best candidates apply the week a posting appears. With Klarna's headcount down from 7,000 to approximately 3,400 through AI-driven restructuring, fewer seats are available and competition is higher per opening. The Glassdoor-reported average process time of 36 days (up to 62 for Graduate Program candidates) means late applicants risk landing offers after seats are already allocated. Set a job alert on the Deel board and the Klarna careers page, and have your materials ready before the window opens. Your CV should follow Klarna's stated format: no photo, no age, with a cover letter in English and university transcripts for Graduate Program applicants.

Which Klarna Internship Programs Should You Target?

Klarna organizes engineering around 11 competences rather than traditional departments, and its early-career tracks reflect that model. The main pipeline is the 12-month Graduate Program, which comes with a permanent contract. Ad-hoc summer internships appear less frequently. Here are the tracks most relevant to early-career candidates:

See open roles on the Deel job board for Klarna. Note that Klarna's AI-first strategy means AI-adjacent engineering roles may carry more weight than in prior cycles.

What Are the Eligibility Requirements?

Klarna's requirements differ between the Graduate Program and ad-hoc internships, but several lines appear across both:

• Education: Bachelor's degree or higher in Computer Science or a related discipline. Bootcamp graduates are explicitly accepted alongside traditional CS degree holders.

• Language: Working proficiency in English (verbal and written) is required. Swedish is not required, as Klarna operates in English across its international engineering teams.

• Technical baseline: Strong development ability in at least one of Java, JavaScript, or Python. Interest and ability to learn additional languages expected.

• Location (Graduate Program): The Graduate Program is based in Stockholm (historically also Gothenburg). On-site presence is required; remote work is not an option for this track. Klarna will provide visa assistance when a position is offered but does not assist with relocation.

• Location (Ad-hoc internships): US-based roles would likely be in Columbus OH or New York. Klarna offers hybrid flexibility for general employees: office, remote within the employment country, or up to 20 working days per year outside it.

Does Klarna Require a CS Degree?

No. Klarna explicitly accepts bootcamp graduates alongside CS degree holders for its Engineering Graduate Program. The emphasis in interviews falls on practical coding ability, system design thinking, and demonstrable experience with AI coding tools rather than a specific credential. What matters most is strong proficiency in Java, JavaScript, or Python and the ability to articulate how you have used AI tools like GitHub Copilot or Cursor to increase your engineering output.

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

Read across four Klarna early-career job descriptions, two SWE variants, one Graduate Program, and one data-focused role, and a distinctive pattern emerges. Programming (Java, JavaScript, or Python) appears in all four, system design and DSA in three, and AI-tool proficiency in three. That last one is Klarna-specific: the company's AI-first transformation means every engineering candidate is evaluated on how they use tools like GitHub Copilot and Cursor in real workflows. Bring the traditional coding skills, but lead with a concrete story about AI-assisted development.

How close is the overlap? The Wayfair project is agent-engineering work that yields the build-and-explain evidence Klarna's AI-competency behavioral round probes for, and the Beats project ends on the data-analysis story a behavioral interview wants.

What Is the Klarna Application and Interview Process Like?

Klarna's interview funnel spans 5 to 6 rounds over 36 to 62 days from application to offer:

1. Apply on the Deel job board. All Klarna applications route through Deel. Prepare a CV (no photo, no age), cover letter in English, and university transcripts for the Graduate Program. Monitor postings starting Fall 2026 for summer roles or Q1 2027 for the Graduate Program.

2. Recruiter screen (30 minutes). Introductory call covering background, compensation expectations, and motivation. Light on technical content; primarily a communication and logistics check.

3. Logic and cognitive aptitude test (12 to 15 minutes). Video-proctored pattern recognition and abstract reasoning assessment, CCAT-style. Described by candidates as a hard filter that eliminates a significant portion of applicants.

4. Technical online assessment (take-home). HackerRank or similar platform with 2 to 3 medium-difficulty DSA problems. Self-paced within a set time window. Alternative format: receive a codebase 24 hours in advance and fix errors.

5. Technical phone screen (60 minutes). Live coding with an engineer on data structures, algorithms, and introductory system design. You must write real code, not pseudocode. Payment-processing contexts like idempotency and concurrent transactions are common themes.

6. Virtual onsite loop (3 to 4 hours). Two coding sessions, a system design round, and a craft deep dive discussing past projects. This round generates most of the hiring signal.

7. Behavioral and AI-competency round. STAR-format questions on technical disagreements, collaboration, and leadership. The Klarna-specific differentiator: you must provide concrete examples of using AI tools like GitHub Copilot or Cursor to increase your engineering output. Vague or hypothetical answers are penalized.

Two skills dominate preparation: DSA fluency with payment-processing flavor (HashMaps, Trees, String Manipulation, idempotency patterns) for the technical rounds, and at least one detailed story about using AI tools for a non-trivial engineering problem for the behavioral round. Glassdoor rates the overall difficulty at 2.98 out of 5, but the logic test and AI-competency round are where unprepared candidates consistently fall.

What Students on Reddit Say

Four community threads show the Klarna hiring experience from the inside, all paraphrased.

How Do You Stand Out at a Company That Hired 3,400 Engineers Through an AI-First Filter?

Three moves, all before a posting opens. First, prepare your AI story now: Klarna's behavioral round explicitly evaluates how you have used GitHub Copilot, Cursor, or similar tools to increase your engineering output, and vague answers are penalized. Build or contribute to a project using AI-assisted coding, document what you built and how AI accelerated it, and rehearse the STAR-format version. Second, clear the logic test on purpose: the 12- to 15-minute video-proctored CCAT-style assessment is described by candidates as a hard filter, so practice abstract reasoning and pattern recognition puzzles until the format is automatic. Third, drill DSA with a payments flavor: HashMaps, Trees, and String Manipulation in contexts like idempotent transaction processing and concurrent payment handling, because Klarna's technical rounds draw from real platform challenges. And the timeline edge: the Graduate Program window is narrow (roughly February through April), and ad-hoc summer postings are filled as they appear. Set alerts on both the Deel board and klarna.com/careers and submit the week a role goes live.

FAQ

Does Klarna offer a traditional summer internship?

Klarna's primary early-career pathway is the 12-month Engineering Graduate Program, not a traditional summer internship. However, ad-hoc summer internship positions do appear on the Deel job board sporadically. Monitor the board starting Fall 2026 for Summer 2027 opportunities.

When do Klarna internship applications open for 2027?

The Engineering Graduate Program is expected to open applications in Q1 2027 (roughly February through April) for a September to October 2027 start. Ad-hoc summer internship postings may appear between Fall 2026 and Winter 2027 for June to August 2027 roles. No official dates are published yet.

How much does a Klarna internship pay?

Klarna has not published intern-specific compensation. The Graduate Program compensates at L1 Software Engineer levels, approximately 52,000 EUR total comp in Stockholm. For US-based fintech internships, the industry benchmark is $35 to $50 per hour. Stockholm benefits include 30 days annual leave, a lunch allowance, pension, gym membership, and RSU opportunity.

Can international students apply to Klarna?

Yes. Klarna states it will provide visa assistance when a position is offered. However, the Graduate Program requires on-site presence in Stockholm and Klarna does not assist with relocation. The company's workforce spans over 100 nationalities, suggesting openness to international candidates.

What is the Klarna interview process like?

The process typically spans 5 to 6 rounds over 36 to 62 days: recruiter screen, a 12- to 15-minute video-proctored logic test, a technical OA on HackerRank, a 60-minute technical phone screen, a 3- to 4-hour virtual onsite loop, and a behavioral round with an AI-competency assessment. Glassdoor rates the difficulty at 2.98 out of 5.

Does the Klarna Graduate Program lead to a full-time job?

Yes, by design. The 12-month Engineering Graduate Program comes with a permanent full-time contract from day one. There is no separate return-offer process. Graduates are already Klarna employees throughout the program.

What makes Klarna's interview different from other fintechs?

Two differentiators stand out. First, a video-proctored logic and cognitive aptitude test (CCAT-style, 12 to 15 minutes) that filters before the technical rounds. Second, a dedicated AI-competency assessment in the behavioral round, where you must demonstrate practical experience using tools like GitHub Copilot or Cursor to increase engineering output.

Is the Klarna internship remote or in-person?

The Graduate Program requires on-site presence in Stockholm (historically also Gothenburg). For general employees, Klarna offers hybrid flexibility: work from the office, remotely within the employment country, or up to 20 working days per year outside it. Ad-hoc internship locations vary but would likely be in Stockholm, Columbus OH, or New York.

Klarna's AI-first hiring bar is rising, but it rewards candidates who come with proof. Spend the runway building evidence: a remote Externship turns 'interested in fintech' into a finished project with an AI-tool story you can point at when the Deel board goes live.
