Klarna interview questions

I applied online and in a week got contacted by a recruiter who asked to pass an IQ test - 30 mins pattern recognition. After that I got a home assignment - a simple "how do you start a project" presentation and an invitation for an interview. The interview in HQ took approximately half a day, and consisted of general "background/skills" questions by 5 different people and review of the home assignment. I got a good feeling from the people I talked with (despite some of them dropped ad hoc due to some HR planning issues) and got assured I will hear back in a few days. Then things got strange. My recruiter went to radio silence (as I learned later he left the company without transferring an ongoing case). Then I started to get messages implying that I am the top candidate, but need to pass one final interview. The concrete date never materialised in 5 months. Overall, it felt extremely unprofessional.

Technical interview had no particular technical questions, we were talking about mostly about my current job/projects without getting much into the details. I was expecting some questions touching areas where Klarna needs developers to have some experience in. It looked like developers were asking the same as for some number of previous candidates without showing any particular interest in what I was describing and more than once I repeated the same details once again because they were asking about things which I have already talked about.
