I applied through a recruiter. The process took 1 week. I interviewed at Klarna (Berlin) in Feb 2019
Interview
First recruiter phone screen, then I was sent two online tests, one was logic (old school irrelevant IQ test even same pattern) and 2nd was 3 questions coding test.
I was replied that I didn't pass.
Because I solved all the coding questions and I was sure of my answers, I even wrote many test cases; I asked for a feedback with scores
The reply was complete nonsense, the comments came I scored 11 of 18 of the IQ and that **my code formatting wasn't good** ! I felt sorry for the recruiter having to carry back such useless feedback.
Assume I wrote the code for the whole question in one line, how about the fact that it was an online exam on a dummy web editor that barely compiles the code, and you say code formatting wasn't good enough ?
If you don't want to hire people just don't run around and recruit and waste our time, instead of giving back unprofessional useless feed backs.
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.

2. You experience.
A few steps with HR. Then 3 different technical steps:

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).
