I applied online. The process took 2 weeks. I interviewed at G-Research in Mar 2017
Interview
Applied to G-Research and got a response the next day. First stage of the interview process was to sit a technical exam. Did well in the first section but not so well in the second one. If you have not done probability, stats and finance for a while, it's necessary to prepare very well, and they'll give you time to do so. I received an email that same day informing me that I had not been selected for the next round.
The interview process was quite fast, I did an initial technical exam on math and coding, then had an another technical interview where they asked math, machine learning and programming question.

I applied online. The process took 5 weeks. I interviewed at G-Research (London, England) in May 2025
Interview
First part was a test evaluating math, Stats, machine learning and financial knowledge. Next part was video interview with some employees but rejected soon after. The next part would be an extension on the first part and I believe final rounds involves a day in the office.
I was asked a Brain teaser type of question. It was quiet difficult but manageable. Great atmosphere. The interviewer was really friendly and nice. I really really enjoyed the interview process would recommend applying.
