I applied online. The process took 3 weeks. I interviewed at First Derivatives (Newry, Northern Ireland)
Interview
-Applied using CV via FD website.
-Telephone Interview (20 minutes)
-Invited to Newry HQ for 2 face-to-face interviews, a written exam and group exercise.
Interviews were all similar i.e. What I studied and why, previous jobs, what you know about company and the CMTP etc.
Written exam is like a logical math exam. I found this very difficult so I think they focus more on the interviews to decide.
