I applied online. I interviewed at Co-op (Belfast, Northern Ireland) in Aug 2013
Interview
Application included long scenario based multiple choice questions including several "right" answers, but some more so than others. Followed by an interview however extremely slow hiring process and took a month and a half longer than promised to start work upon being confirmed a successful candidate. Very awkward for people in the jam. The management at that particular coop soon was soon shuffled around and my experience may be an anomaly but beware.
