I applied online on 21st July. Received preparation material on 26th July, which include probability theory, martingales (stopping times), Markov processes (gambling problems), ordinary least squares regression, estimation theory, modern portfolio theory (CAPM and APT) and C++ (operator overloading and backtracking); however, none of the links to the lecture notes worked. I contacted G-Research on 26th July via email and jobvite.com, and 11th August via phone to inquire about the progress of the application, yet no reply. As a result I made a fresh application on 17th August, hopefully this time I'll get a interview.
Interview questions [1]
Question 1
Probability theory, martingales (stopping times), Markov processes (gambling problems), ordinary least squares regression, estimation theory, modern portfolio theory (CAPM and APT) and C++ (operator overloading and backtracking)
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
