I applied through a recruiter. The process took 3 months. I interviewed at Klarna (Madrid) in Jun 2021
Interview
I would definitely NOT recommend starting a process with them.
I was contacted by a recruiter. The process is extremely long, as others have already stated, which does not make sense.
I did 5/6 rounds of interviews, some of them asking very similar questions to previous ones, so the process could easily be shortened and simplified. These included:
1. A first contact call with the recruiter about my experience/career
2. An online assessment to do on your own time
3. An online IQ test (this done with someone watching you in a call)
4. A pair programming/skills technical interview
5. A system design/api design technical interview
6. Behavioural/cultural fit interview with eng. managers
7. Another behavioural/cultural fit interview
The engineering people seemed nice and those interviews were quite fun, spending some time discussing the problems.
Unfortunately, the feeling I got from HR and eng. managers was quite different. They seemed arrogant and extremely pompous about working in the company, as if they were curing cancer with an app.
After two weeks of no response from them I was told my application was going to be "held off" for some months. I asked for more feedback about my performance in the process but I got no response from them.

Question 1
- Could you tell me one time you proposed a change based on user feedback
- Design an API service where you get a POST with some user payment data (amount, etc.) and you have to design the system and the request/response structure.
I applied online. I interviewed at Klarna (Estocolmo, ) in Mar 2026
Interview
The process involves several stages. The first is an online logic test to evaluate your pattern recognition skills. Subsequently, HR will invite you to a remote online meeting so they can get to know you better. They do not hire for a specific team/role and will instead see if you match with any of their teams.

Question 1
1. What do you know about Klarna
2. You experience.
A few steps with HR. Then 3 different technical steps:
- Challenge to complete at home
- Live coding
- System Design
The system design interview was the longest, about 2 hours. The idea was discussing how to implement a new feature on a website.

Please implement a new endpoint on the codebase that we sent you. Also, fix the issues present on the code.
I applied online. I interviewed at Klarna (Milán) in Oct 2024
Interview
Il contatto delle risorse umane mi ha spiegato tutto del processo in anticipo, affinché mi fosse chiaro. Dopo averci conosciuti ho partecipato a tre colloqui tecnici da remoto, su: il disegno dei sistemi (system design), la programmazione (live programming) e il comportamento (STAR behavioural interview).
