I applied online. The process took 2 months. I interviewed at Eaton (Birmingham, Angleterre) in Feb 2016
Interview
Application online followed by a phone interview then you are invited to an assessment day. Throughout the day you partake in various group tasks such as presentations, and some individual testing. Nothing too complicated, just make sure you are inputting well within the group. A large amount of people are sent home at lunch, with a selected few taking part in interviews in the afternoon.
