I applied through a recruiter. The process took 4 weeks. I interviewed at G-Research (London, England) in Jul 2017
Interview
Online test, followed two on site interviews.
Each onsite interviews were a mixture of knowledge questions and pen and paper style interview question taken by members of the team, role was for. Passing this first stage of each interview, the later parts took the form of informal chats with members of management and show around the office.
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.
