I applied through a recruiter. The process took 6 weeks. I interviewed at G-Research (London, England)
Interview
Basic test consisting of stats and basic financial questions, then interview with some quants. They gave me brain teasers and more stats questions. I got passed the interview and 3 quants, but in the end they didn't hire me, although they said that I would fit in well.

I applied online. The process took 5 weeks. I interviewed at G-Research (London, England) in May 2025
Interview
First part was a test evaluating math, Stats, machine learning and financial knowledge. Next part was video interview with some employees but rejected soon after. The next part would be an extension on the first part and I believe final rounds involves a day in the office.
I was asked a Brain teaser type of question. It was quiet difficult but manageable. Great atmosphere. The interviewer was really friendly and nice. I really really enjoyed the interview process would recommend applying.
