Very thorough interview process. Good experience overall. A series of questions with the VP of Analytics.
The interview started out with a series of general quesitons about management style. It then moved on to personality-type questions.

Entretien
First, they ask whether you are comfortable working in the office five days a week, as the position requires regular on-site attendance. After that, candidates complete a 50-minute written assessment focused on Machine Learning, Mathematics, and Statistics. The assessment evaluates your understanding of core concepts, problem-solving abilities, and analytical thinking rather than coding skills. It may include questions on probability, hypothesis testing, regression, model evaluation, machine learning algorithms, and other data science fundamentals.
