I applied through a recruiter. I interviewed at Winton Group
Interview
It was a long process
2 technical rounds online - mostly related to Python, with lots of questions, like multiprocessing, testing, pandas, etc.
4 onsite rounds in their office - each round was a similar pattern - a python exersice, and pandas case study.
I applied through a recruiter. The process took 3 weeks. I interviewed at Winton Group (London, England) in Mar 2026
Interview
1. Recruiter conversation
2. Codility tes
3. HR interview. Quite straightforward.
4. Interview with the hiring manager for the role. Technical 45 mins interview for live coding question. He was 10 mins late to begin with, Constantly interrupting me mid interview and penalise me for not implementing the solution the way he wanted it. Really gave me a bad taste of what the culture would look like at Winton.
