I applied through an employee referral. The process took 5 days. I interviewed at Atos (Londres, Angleterre) in Apr 2013
Interview
The process is the same for almost every people. After the phone interview, it starts with an AC including a personal interview and presentation. The case for the presentation is always the same. You should try to find it our in advance. If successful you have an interview with a partner which is the final one.
Interview questions [1]
Question 1
The critical point is to convince the partner you are the right choice. My partner was friendly and didn't make any specific terrible question.
