Completely ghosted me after 1-hour interview where they promised reply soon. No information back at all about the decision. Shows all you need to know about the level of "professional" they are.

Klarna have an odd process. Some good interviews, but more upfront detail about them would be beneficial. The sourcing test is managed by a Sourcer, my experience was that this person is not a skilled interviewer. To improve experience I would suggest to have this step as a sourcing test only. I was informed I would have received an offer if my comp expectations were lower. Which then just meant the process was a waste of time and something that could have been communicated up front. So communicating the ranges for each role you are being considered for would be helpful and potentially reduce churn.
