I applied online. I interviewed at Klarna (Stockholm, Stockholm) in Apr 2017
Interview
Firstly I got phone call from klarna, then I went to the career day. It is a really long day, which you can met a lot of people there. After that you will get still some interviews. But do NOT feel confident about the offer until you assigned the contract.
Interview questions [1]
Question 1
what will you do if you have full access to Klarna's data?
