The process took 5 days. I interviewed at Klarna (São Paulo, São Paulo)
Interview
DO NOT WASTE YOUR TIME
A recruiter sent me an email and scheduled a meeting to talk about the company, my motivations and the next steps in the process. I was given a take home challenge via Qualified and was expected to recognize room for improvement and refactor some code. After that, I had a weird "supervised" logic test, a series of images where I needed to select the next pattern.
The process stopped here. I received an email with a generic rejection message. I wasted 3 hours of my time on this weird process.

The process involves several stages. The first is an online logic test to evaluate your pattern recognition skills. Subsequently, HR will invite you to a remote online meeting so they can get to know you better. They do not hire for a specific team/role and will instead see if you match with any of their teams.

Question 1
1. What do you know about Klarna
2. You experience.
A few steps with HR. Then 3 different technical steps:

I applied online. I interviewed at Klarna (Milan) in Oct 2024
Interview
Il contatto delle risorse umane mi ha spiegato tutto del processo in anticipo, affinché mi fosse chiaro. Dopo averci conosciuti ho partecipato a tre colloqui tecnici da remoto, su: il disegno dei sistemi (system design), la programmazione (live programming) e il comportamento (STAR behavioural interview).
