I applied through a staffing agency. I interviewed at G-Research (London, England) in Jul 2017
Interview
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.
Interview questions [1]
Question 1
Signed an NDA, but most of it is the kind of stuff you can prepare for by practising on hacker rank.
The interview process was thorough and well structured. It focused primarily on data structures and algorithms, and the level was broadly in line with what you would expect for a software engineering interview of this type. I cannot share specific details of the questions, but standard preparation in algorithms, data structures, problem solving, and coding under interview conditions should be sufficient. Overall, it felt rigorous but fair.
There were mostly algorithmic questions to be solved on a whiteboard. Then, after a lunch with a couple of the junior staff, the tell you whether you’re into the next round. There is also a test beforehand.
2-3 parts depending on team. Pretty in depth on topics. 2 coding rounds I believe. Interview process is fairly quick. It’s not a process that takes 3-4 weeks. 2 weeks max, 1 week if you’re really adamant.
