The on-site interview was definitely one of the hardest interviews I had for finding a quant researcher position. The overall interaction with the company was pleasant and two of the three interviews were also very enjoyable with the interviewers clearly knowing their stuff. However, the third interviewer seemed to be absent, was unfamiliar with basic statistics expressions and generally made a weak impression. Curiously, I got the worst feedback from this third interview (even though the first two ones were probably also not good enough to make it to the next round). Overall, this experience ruined an otherwise pleasant interaction with the company.
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
