I had 6 interviewers and each asked different questions. I was able to answer due to my experience at Amazon. I enjoy the business case analysis as well. Having a customer mindset is key to deliver a good case overview.

Applied for an open position posted on their webpage, first step was 3 online tests. I was not living in Sweden at that time so I had booked interviews with HR and the hiring manager the same day. I have understood that normally HR meets the candidate first (or at least used too). The person conducting the HR interview was mainly speaking about how great Klarna is and posed limited amount of questions to me. The hiring manager had a combined case and guesstimate questions for me. Next step was interview with the Chief Risk Officer which was done over Skype. Nothing out of the ordinary, testing my interest and logical thinking.
