I applied online. The process took 3 months. I interviewed at Klarna (Stockholm, Stockholm) in Nov 2023
Interview
The interview process was the following:
1. Short interview with recruiter, about 30 minutes. Mostly introduction and presenting my background.
2. Reasoning test & take home code assignment done in Kattis.
3. First round technical interviews consisting of live coding, system design and behavioral interview (could be done in random order). Each of these interviews is about 1h.
4. Team fit and manager interview where you get to meet the team and manager(s) that you might end up working with.
The whole process was very long and tedious. I applied for a hybrid-work position in one city, but the position got removed and ended up getting an offer for the same position in another city for on-site work. Wasted about 3 months because of the very long interview process and they couldn't offer the position that was initially applied for. Don't waste your time, especially when they don't live up to leadership principles that they promote.

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.

A few steps with HR. Then 3 different technical steps:

The system design interview was the longest, about 2 hours. The idea was discussing how to implement a new feature on a website.

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).
