I applied through a recruiter. The process took 1 week. I interviewed at Klarna (Stockholm, ) in May 2016
Interview
In house recruiter got in touch, did an IQ test the next day, got called into an interview after 5 days. Interview was at Klarna Stockholm office. 2 developers and myself crammed into a small interview room, with a glass board that is un-writable with marker pens, extremely claustrophobic. The ensuing discussion was quite ok but got the feeling that the people doing the interview was not well suited to conducting them.

it consisted of 3 parts, HR, technical, behavioural. The technical part was a leetcode hard problem but they did not expect a hard solution. The behavioural was related to leadership principles similar to most companies.
I applied through a recruiter. The process took 4 weeks. I interviewed at Klarna (Parijs) in Oct 2025
Interview
I had a second experience with Klarna. After the ghosting of last year, Klarna reach out again for a SWE position. The same happened. After the first discussion, I have been told again to book a slot for the second round. And then... no news from anyone.
Second ghosting. Klarna has a terrible HR process and policy.
I feel like I dodge a bullet here. The work environment might be pretty toxic if it is aligned with the HR practices.
