I applied through a staffing agency. The process took 4 days. I interviewed at E.ON (Nottingham, England) in June 2013
Interview
Long through an agency, telephone, in person, online tests, final in person interview. The questions were fairly standard, and related to the work to be done. Tests were done a few times to ensure that the correct candidate was chosen, and times are tight, however with practice it is fine. It's a basic maths and English test, timed, and I passed with not much prep.
