I applied through a recruiter. The process took 2 months. I interviewed at G-Research (London, England)
Interview
I have interviewed at G-Research. The process involves a written test followed by many one-to-one interviews over a few visits. The interviews are both technical and motivational. Expect the process to be in-depth, taking a few weeks if not months, and to be asked challenging brainteasers and technical questions.
I have been treated well by everyone I met. Everyone I interviewed with was clearly smart, both researchers and management.
Interview questions [1]
Question 1
I have signed an NDA. The example test on their website provides good examples, though some of the questions in that test are hard and you would not be expected to be able to do them without any guidance. G-Research or your recruiter will advise that you prepare on some basic finance material and while it may not be absolutely necessary, it is a good idea to do so.
I applied online. I interviewed at G-Research (London, England) in Mar 2026
Interview
The interview process consists of multiple stages with hard quantitative bars to be met. After CV screening, they send you their proprietary online assessment of 10 MC. Some questions seem unusual, some are intentionally tricky, but most are similar to standard quant brainteasers and you can pass if you have really grinded through standard material. Then, there is an online interview with a quant which will ask you technical questions in barrage. The bar probably depends on your answers' grades and how many questions you can answer. I did not expect some questions, so I was caught unprepared and I fumbled spectacularly.
lots of prob stats, i prepared using the greenbook, but I guess i didnt do as well as i thought i did
I also did some review of combinatorics and statistics, but still unsure about my performance
Fairly straightforward. The questions were pretty standard for the most part, similar to what you would see in other quant researcher interviews, maybe a bit more on the stats end
