I applied online. The process took 3 weeks. I interviewed at Klarna (Berlín) in Nov 2020
Interview
1. IQ test with a follow up from an internal recruiter
2. Quick 15-minute interview with the said recruiter
3. Home task, a set of three Leet coding challenges
4. Cultural fit interview (45min) + Technical questions and pair programming trying to solve 2 more leet coding challenges(1 hour)
The interviewer might tell you he just wants to see how you think, but if you partially finish one of the leet coding challenges while explaining how you would finish it. You will be rejected. So try to solve them any way you can.
Don't extend yourself talking in the Pair Programing exercise you will not be granted any extra time to finish.
If you think leet questions are a valid way to judge technical expertise, try it out you will fit right in.
(leets: rotating strings, sorting array by the sum of digits, finding a valid route in
a list, last 3 elements in a deep nested structure, keys and rooms)
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.
Interview questions [1]
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.

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).
