I applied through a staffing agency. The process took 1 week. I interviewed at IMCD Group (Sutton, London, England) in Dec 2015
Interview
Started with a maths test and a few competency questions. Other than that it was a pretty standard interview with someone from HR and the line manager. Maths test isn't too hard, things like working out percentages and converting. Competency test wasn't hard either, basically just use your common sense.
