I applied through a recruiter. The process took 1 day. I interviewed at Klarna (Stockholm, Stockholm) in Aug 2015
Interview
Someone from Klarna reached out to me when they saw me attending a conference nearby. After that it went very smoothly. From a phone call, to arranging a day-long set of interviews at their HQ.
I got an intro, a lunch interview with a manager, a pair programming interview, then 2 set of technical interviews (whiteboarding mostly), and then an interview with the VP of engineering.
A few days afterwards I received an offer.
Best interview pipeline I've been through so far.
Interview questions [3]
Question 1
How could you implement unique id's over a set of N servers?
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 (Paris) 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.
