I applied online. The process took 1 day. I interviewed at Atos (London, England) in Jan 2016
Interview
Quick interview, just some simple questions: a few about times I've worked in teams and and a bit about the security clearance procedures I may have to go through. She was quite gentle, told me to phrase my answers in terms of situation, actions and conclusions. I was told it would take up to 40 mins, but it was over in 23. I was told that getting an invite to a face-to-face interview would also depend on my performance in the numerical and verbal reasoning tests I had already taken.
