I applied online. The process took 1 day. I interviewed at FDM Group (London, England) in Nov 2015
Interview
Three interviews lasting five minutes each. Just be yourself and you will be fine. There are three separate interviews to eliminate bias as there are three separate interviewers. There was an hour long maths exam, an hour long IT exam and a half hour numerical test. The numerical test just requires multiplication and long division, nothing at all difficult.
