I applied online. The process took 4 weeks. I interviewed at Atos (London, England) in Sept 2012
Interview
1) Online application form
2) Telephone interview - Standard questions about Team work, Leadership, Customer satisfaction etc.
3) Assessment Centre (run by Alexander Mann). Team exersize, 3 "mini" interviews and a role play. All very similar to other assessment centres (other than the Mini interviews which I found easier, each person focuses in on an area eg. background, why Atos, competencies). One presentation.
4) Offered job and told location
5) Chat with new manager
6) Chat with Buddy
