Klarna Developer interview questions

I was approached by the recruiter a few times. Then he has done an introduction interview. I agreed to do test algorithms on Qualified. And never heard them back after I successfully passed the tests

First step was a normal phone screen with a recruiter, we discussed myself, Klarna and the role in general. After that I recieved instructions to complete an IQ-test from Kattis. 15 logical pattern questions. Your standard logical IQ test really. Upon completing that I was granted access to step 2, which consisted of two separate coding challanges on a third party coding challenge platform. Focus was on test driven development, so it was designed around unit test executions. Both challenges had a time limit of 2 hours. I used the time fully. So 4 hours in total, a considerable chunk of time to set aside if you work full time. I completed the challenges and sent them in. Haven't heard a word from Klarna since. Not even after contacting them again asking about an update. Very unprofessional.
