Technical Coding Behavioral
So the interview had 3 parts: first, an HR chat, then a technical challenge, and finally a behavioral round. The technical part involved a LeetCode hard problem, though they weren't expecting a super complex solution. The behavioral section was about leadership principles, pretty standard stuff.

Behavioral
I've had a second experience with Klarna, and like last year's ghosting, they reached out again for a SWE position. The same thing happened: after an initial discussion, I was told to book a slot for a second round, and then... no news from anyone. A second ghosting. Klarna has a terrible HR process and policy. I feel like I dodged a bullet here, and the work environment might be pretty toxic if it aligns with their HR practices.

Behavioral Technical Coding
The interview process started with an introduction interview where we discussed the role, my experience, skills, and expectations. Then, there was an abstract reasoning assessment and a coding test. The abstract reasoning test was an online test to identify the next pattern within a limited time; it's advisable to practice with a few example tests beforehand. The coding test mainly involved developing a Spring Boot application, though a fully end-to-end application wasn't expected. The key was to understand the requirements properly and consider concurrency, scaling, and validations during implementation. Finally, a technical interview focused on discussing the implemented application and exploring potential improvements.
