    Financial Forecasting Challenge - G-Research

    Can you predict the future? G-Research has launched what we hope will be an interesting and fun forecasting task to provide you with a flavour of one of the types of problem we work on. We'd like you to predict y (an element of the return of a financial data series) from a number of features we'll supply you with.

  • Can we trust AI if we don't know how it works?
    David Stern, one of our Quantitative Research Managers was recently featured in an article by the BBC:

    Can we trust AI if we don't know how it works?

    We're at an unprecedented point in human history where artificially intelligent machines could soon be making decisions that affect many aspects of our lives. But what if we don't know how they reached their decisions? Would it matter? Imagine being refused health insurance - but when you ask why, the company simply blames its risk assessment algorithm.

Leon - Quantitative Researcher

"Having started my university education in Engineering at MIT, finance didn’t initially seem like an option. But, after a discussion with my peers, I steered my PhD research towards more applied maths topics – positioning myself for a finance role.

There was a lot I didn’t know about the G-Research, so I gained insights from those who interviewed me. They all came across as intelligent, curious, and interested in exploring problems from different angles. I figured if people like this enjoy their jobs then I most certainly will.

And over two years in, there’s nowhere I’d rather be. The atmosphere is very relaxed and, as a quantitative researcher, we can pretty much spend all our time doing what we like the most: finding solutions to interesting and challenging problems. There are no office politics and the performance metrics couldn’t be clearer cut, which is a big motivational factor."

Samantha - Software Engineer

"I completed a BSc in Natural Sciences and then went on to do a major in Computer Science at the University of Birmingham. After university, I worked for a large bank but quickly realised I was looking for a more exciting challenge. After speaking to a friend who worked at G-Research, I knew it would be the place for me.

My favourite part of working for G-Research is the great working relationship we have with the people we write software for: it feels like we’re working with them, not for them. I also really enjoy the structure of my working day and the proportion of my time spent writing and designing my own code."

Roshni - IT Service Desk Team Lead

"After completing a BSc (Hons) Degree in Network Management and Security at the University of Middlesex, I was fortunate to be put forward for the IT Service Desk position at G Research. My previous role was working within an IT Service Desk, however since joining G-Research I have discovered that this is not a traditional service desk. We are supporting and working with cutting-edge technology in a fast paced environment, making the role both challenging and exciting all the time."

Simon - Cyber Investigation and Response Analyst

"I was looking to move into a pure Information Security role after being a Systems Engineer at a company that made HSMs. G-Research looked like an attractive place to work because they put themselves forward as needing security to protect their core assets – as opposed to security to maintain some arbitrary compliance checklist.

After a few interviews, I was convinced that G-Research was the place I wanted to be. I knew that working alongside the people who conducted the interviews would help me grow professionally. The best part of working at G-Research is the calibre of people that work here. I have learned so much since starting here and have been supported every step of the way, enabling me to pass my CISSP, Certified Incident Handler (GCIH) and Network Forensic Analyst (GNFA) exams."

    Positive Outlook

    I have been working at G-Research full-time (More than 3 years)


    Positive working atmosphere - people help each other out, no prima donnas
    Smart colleagues - the standard overall is by some way the best I've ever had in a workplace. it's a great place to learn
    Sensible work/life balance - the emphasis is on sustainable work, no-one is expecting any death marches
    I find the day-to-day work interesting and challenging - we are trying to get and stay ahead of others in our sector, so things don't stay still for long
    Great location
    It's growing, so there are opportunities for those who might want to end up managing others
    Solid business model - I think the company is very well placed for the short/medium term (which is as far ahead as I care to predict)
    Decent pay
    Reasonable selection of soft drinks, although I am still not sure whether Diet Lilt should have made the cut


    Security concerns mean home working is off the menu. Not a problem for many, but
    a major drawback for me
    It's growing, so it's not as small as it was - not a problem for me, but some might prefer a sub-100-employee type setup

    Advice to Management

    If I do personally drift away from G-Research, it will most likely be because of a lack of flexibility in working patterns, whether it's not allowing home working or everyone having to work 5 full days every week.. As the workforce ages (and so more of them have kids), this will become a more general problem in G-Research. Don't let this creep up on you!

    Software Engineer Interview

    Anonymous Employee in London, England
    Accepted Offer
    Positive Experience
    Difficult Interview


    I applied through a staffing agency. I interviewed at G-Research (London, England) in July 2017.


    Online test, followed by 2 on site interview sessions each consisting of 3 interviews of an hour each.

    The online test was easier than similar tests I have taken at other companies, but seemed pitched fairly well to weed out weak applicants without making it unreasonably hard.

    The first day of interviews were all with members of the team I applied for, and all almost exclusively technical.

    The second day was a mixture of technical interviews and more qualitative interviews with senior staff.

    Generally a well organised process.
