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.
