I applied online. The process took 1 day. I interviewed at MBDA (Bristol, England) in Feb 2016
Interview
Online application/tests, followed by assessment centre. Online application simple enough (usual filling in of forms etc), similarly simple with the test. Assessment centre involved a group task with the other interviewees, a presentation to some employees, and a 2 to 1 interview. A brief summary of the possible job was also given.
