I applied online. I interviewed at Klarna (Estocolmo, ) in Apr 2022
Interview
First I was given a remote logic test to complete and then there was the first remote interview. After the interview I was assigned two tasks - logic test (again!) and a data science task. The logic test was the same one, but this time, Klarna's employee was watching me through the camera. Why do the same test twice? The data science task took 10+ hours because the dataset required a lot of exploration to be understood, there were a lot of missing values, it was very imbalanced, etc. The task was to train a credit risk model and to deploy it to some cloud service provider. It required much time to come up even a simple solution.

Question 1
Train a credit risk model and to deploy it to some cloud service provider.
Onestamente uno dei peggiori iter mai affrontati. Screening HR rimandato più volte con una latenza di risposta incredibile. Ricevo la comunicazione 30 minuti prima del colloquio, fornisco immediatamente nuove disponibilità, ricevo risposta dopo 4-5 giorni. Successivamente ricevo un assignment abbastanza impegnativo da fare entro 7 giorni lavorativi, la cui traccia però è assolutamente insufficiente a comprendere bene l'obiettivo e il contesto. I dati su cui lavorare sono pieni di anomalie, ho pensato che potesse essere parte dell'assignment e chiedo spiegazioni in maniera molto proattiva e mostrando di averci sbattuto la testa. Anche in questo caso ricevo risposta dopo giorni e stringatissima (tipo 3 o 4 parole), assolutamente inutile a risolvere i miei problemi. Concludo comunque l'assignment evidenziando le cose che non mi tornano, consegno e non ricevo mai più risposta.
After a brief conversation with a recruiter, I was invited to talk to a hiring manager, who was really rude. He asked for my salary expectation, and I said "I am currently getting xxxx", and he said "you are not worth that salary."
A lot of steps that you have to prepare for. It takes time.
HR, ML task, Technical interview, Klarna fit interview, another technical interview, and finally team fit interview. You have to prepare well for each process to stand a chance.
