I applied through a recruiter. The process took 6 months. I interviewed at Klarna (Madrid) in Dec 2023
Interview
5 phases all passed (a process that took almost half a year). I was told I would be offered to the next team that had an opening and would interview with them, getting hired if there was positive feedback.
Well it's been half a year since then. Every email requesting an update came back with a different excuse (hiring person was on holidays, new budgets being approved, I personally forgot, etc).
At this point I have to conclude that they aren't actually hiring, just keep a constant recruiting loop so they have someone with a finished interview available whenever needed.
Extremely disrespectful to people going through the process.

Question 1
System design interview. If you know the usual resources it's pretty standard. Designing a security system for payments.
I applied online. I interviewed at Klarna (Stockholm, Stockholm) 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.

I applied online. I interviewed at Klarna (Milan) 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).
