Klarna Software Engineer interview questions

They responded after a month that they want to continue with my application, which was okay from my side. But after their response, they sent me a coding assignment, and after I submitted my solution they never got back to me. It's just unprofessional to me.

This was an on campus drive. A coding test was conducted on hackerrank of 2 questions with time limit of 90 minutes.. questions were not too easy.. i would say medium.
