Contacted by their HR department and asked to take a technical sit-down exam consisting of quite difficult mathematical, statistical and algorithmic questions. Signed NDA, so not allowed to disclose specifics on the questions. However, there are previous exams on their website to use for preparation. Their staff is really accommodating and helpful.
Interview questions [1]
Question 1
Wide range of tough questions on probability, statistics and algorithms.
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
