I applied online. The process took 1 day. I interviewed at G-Research (London, England) in Oct 2019
Interview
Had 4 interviews with all the interviewers basically asking the same questions repeatedly. Think they had more planned for the day but there was a gas leak so i guess they could only improvise and do the interviews.
Interview questions [1]
Question 1
simple networking questions eg. what is subnet mask UDP etc.
