Online Assessment, behavioral interview, technical interview, then a day of technical and behavioural interviews. Online assessment comprised of coding questions, guessing what number comes next in a sequence, probability questions and finally some games.

Question 1
From the behavioural interview: What are three qualities a quantitative researcher needs to have?
The process is hard but exciting. The first online assessment contians bits of coding, quick game skills aswell as logic tests. Overall a good process, but very challenging. D d

Two medium questions and one hard question.

Then logic questions.
