Klarna Developer interview questions

A headhunter from another company working in part with Klarna contacted me first. Convinced me to apply for the position. First got a logical test to be done on computer in 15 minutes. Then got a link to online coding site of 3 questions. After solving them, was invited for interviews. Just the day before the interview, was contacted by the headhunter who told me that somehow they changed their mind. Mind you, up to that point, I was yet to see a human from Klarna let alone talk to one. They are like robots and treat you like one. Very unprofessional company and attitude. Just wasted my time on silly questions, do not bother. They did not even give a reason why they changed their mind. I had heard similar experiences about their unresponsiveness and ignorant attitude. Seems they were true. Avoid this company like the plague if you value your career and sanity..
