I applied through a staffing agency. The process took 2 weeks. I interviewed at Marshall Wace in Sept 2025
Interview
First round was a Codility test with 3 questions. There is a culture, technical, and final interview beyond that. I was contacted by a recruiter who encouraged me to have a go.
Initial Coding test. Three problems, medium/hard.
Then Maths test. I think around 20 questions and you have to be fairly quick. About 1 min per question.
Then HR interview going over previous projects and general behavioural questions. Did not get through after this.
Interview questions [1]
Question 1
Describe a time when you had to be innovative in a project?
The first step was online technical exam. The exam was very diffucult and contains more problems than you are supposed to solve. This makes harder to focus on only a couple of questions. The second step was codility test and the third step was online data exam
