I applied online. The process took 2 weeks. I interviewed at G-Research
Interview
The first stage was to take a 90-minute exam. The first part was pretty straightforward. The second part gave a few harder problems and you had to pick one to solve--if you can spot the trick they're not bad.
Round two was a video interview. This was more of a behavioral interview. The interviewer went over my education and experience. Some technical questions were woven in. For example, he'd go into my programming experience then ask a question about object-oriented programming. This was scheduled for an hour, but we only talked for half that time. The next day I got a rejection e-mail that had a cryptic comment about them not being convinced about my motivations.
While I will praise their efficiency--it is truly marvelous how quickly they got back to me and moved through the process--I found the commentary on my motivations rather rude.

You will be reminded that you would have signed an NDA prohibiting you from sharing any confidential information, including details of test questions. We have the right to action the NDA, therefore would ask that you remove the interview question as soon as possible.

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
