I applied through a staffing agency. The process took 1 day. I interviewed at Clarion (London, England) in Sep 2015
Interview
Bought into interview room asked relevant questions why do you want to work here etc? Then moved onto technology based experience. From there it was a simple matter of seeming personable and approachable. Keep a cool head, don't over embellish and show confidence. They want to see personality as well as an interest in technology. Don't have to know massive amounts of detail but some knowledge of industry/research will go a long way.
