I applied through a recruiter. The process took 4 weeks. I interviewed at Visa Inc. in Mar 2020
Interview
A recruiter found my resume in their databases and contacted me for the position. The first round is just for HR screening. There wasn't technical questions. The second round was called from a senior data scientist. She introduced their team first and asked some technical questions.
Interview questions [1]
Question 1
Introduce yourself, some basic SQL and a business problem
Prima di un contatto con HR ti fanno fare un test di codice con preparazione dati e l'uso di un modello di machine learning. Il punteggio viene comunicato subito. L'HR mi ha comunicato che non ho fatto un punteggio abbastanza alto.
