I applied through a staffing agency. The process took 2 weeks. I interviewed at ENGIE (Leeds, England) in Mar 2014
Interview
This involved an online verbal reasoning and numerical reasoning test which were standard. There was only a first interview which was conducted by a senior operational manager and a supervisor. The interview was competency based and a long series of questions were read from a script with explanations why each question was being asked. Everything was friendly and professional.
