I applied through a recruiter. I interviewed at G-Research (Padua) in Mar 2016
Interview
The first steps of the interview process are a written test and an interview. They are about testing the candidate skills and fluency on statistical, mathematical, financial, coding background, plus logical reasoning through brain-teasers. The interview process requires a good and deep preparation on the typical topics of quantitative interviews.

The interview process was quite fast, I did an initial technical exam on math and coding, then had an another technical interview where they asked math, machine learning and programming question.

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.
