This article seems to miss some really important points regarding the layoffs.
A majority of the employees that were laid off were recent hires which is evident from the publicly available "Klarna Affected Employees Input Form" available here [1].
It appears that Klarna went on a hiring frenzy and had to reverse that decision. Out of the 560 responses almost 100 are labeled "Talent Acquisition"/"Recruitment".
