Very lengthy, throughout process. Frustrating too. Received a phone call by a recruiter in the UK. Nice chap. He sold me the company as the next big thing in Fintech, a leader in Europe and expanding in the US. First I took a "logical thinking" test online and hit a good score. Secondly, they gave me an implementation assignment. Since I came this far, I thought I should take it. I'm not much of a programmer so I spent about 10 hours on it. I discussed my assignment with the Sales Engineering team.. nice folks. My results were "passable" so they flew me over to Columbus for interview and whiteboarding gexercises. I spoke to the Director of customer service and the Sales Engineering team. For what I could tell I was by far the oldest person around (I'm 43). Very millennial atmosphere. I got drilled for an hour or two.. resolved a logical problem on the board and discussed some payment network flows (and where Klarna product is positioned). The next day the recruiter called me and told me Klarna decided to give the position to an internal resource. That's for the best because by the end of the interview I already knew that Klarna was not the place for me. Too bad I spent 30 hours in the process, including in-transit time, to find that out. The upside is that this interview process made me look at my current job with a fresh and more positive perspective.
