I applied through a staffing agency. The process took 1 day. I interviewed at CDW (London, England) in Jul 2016
Interview
Very long day, 9-6.30 pm - spent most of the afternoon doing nothing but waiting around.
Started off by introducing yourself and saying an interesting fact about yourself followed by a group task where you have to sell an iPad to a retail company then you do a 3 min presentation about why they should hire you and a small interview.
