How difficult are G-Research Quantitative Researcher interviews, and what is the offer rate?

Candidates report the difficulty as difficult across 98 reported interviews for the G-Research Quantitative Researcher process. The reported offer rate is 10%.

What is the interview loop for G-Research Quantitative Researcher roles, and what happens in each stage?

The loop starts with an Online Assessment that acts as a quantitative gatekeeper, covering probability, statistics, and programming. If you pass, you move into technical interviews that assess research capabilities and technical fluency, and some rounds may be triage. The final stage is meetings with senior researchers or management to evaluate cultural fit and long-term potential.

What topics does G-Research test for Quantitative Researcher, especially in probability, stats, and ML?

Preparation should emphasize Probability Fundamentals and Statistical Estimation and Interpretation. Other commonly tested areas include Machine Learning Fundamentals, Optimization (Minimizers and Loss Functions), Neural Networks and Dropout, and Linear Regression. Candidates also see Kelly criterion questions and Adam optimizer and training dynamics.

What coding and algorithms questions should I expect for G-Research Quantitative Researcher?

Expect Python-heavy questions with an emphasis on efficiency, data structures, and clean, readable code. The public sample questions include solving a medium LeetCode style problem with time complexity, evaluating continued fractions from coefficients, and implementing a multiclass version of logistic regression.

How should I handle model evaluation and research integrity in G-Research Quantitative Researcher interviews?

You are expected to discuss how you avoid data leakage, prevent overfitting, and validate models. The guidance stresses being able to explain your research methodology and maintain skepticism of your own results, not just compute metrics. Public sample questions also probe topics like how to deal with fat tails in linear regression and choosing loss functions under outliers.

What compensation can I expect for a G-Research Quantitative Researcher role?

Candidate and job-posting reports show base pay starting at $150k, with total compensation reported up to $195k. Pay can vary by level and location, but the reported range you should anchor on is $150k base and up to $195k total.

Difficult Positive London, England

After my CV screening, I was sent a proprietary online assessment with 10 multiple-choice questions. The time pressure wasn’t the main issue so much as the vibe of the questions: some felt unusual and a few were clearly designed to trip you up. I could see how the better ones mapped to standard quant brainteasers, but I still got caught off guard by what they asked, and I fumbled more than I expected.

Not long after, I had an online interview with a quant that felt like a barrage. The interviewer kept moving quickly through technical questions, and the bar seemed to be tied to how many I could answer correctly and how well I performed overall. I remember walking out feeling like I wasn’t fully in sync with their pace or the way they chose the questions. I didn’t get an offer, and the biggest takeaway was how easily one unexpected curveball could derail an otherwise decent run.

Difficult Positive Italy

My process started with a timed multiple-choice test. I had 10 questions with five answer options and ninety minutes to get through them all, with only basic proctoring that seemed to track things like switching browser tabs. The set mixed straightforward items with questions that needed real math knowledge—there was at least one problem where I had to determine a minimizer of a cost function and reason about how the cost scaled with the initial condition.

After that assessment, the interviews moved into a mostly technical sequence. I remember doing several coding-related questions too: most were manageable, but one needed Python-specific knowledge. In my run, I ended up getting rejected after the second round, and that second round itself included three interviewers—so it felt like the process narrowed quickly. Overall it was difficult and more technical than I wanted to be caught unprepared for, and even when I could handle parts of the material, the pressure of keeping up across rounds made it hard to recover from mistakes.
