I applied online. The process took 2 weeks. I interviewed at ALTEN (Brussels) in Dec 2013
Interview
I applied online via ALTEN's website and I was very surprised to be contacted within the next couple of days . Interview was scheduled two weeks after my initial online application. Interviewer mostly asked questions about:
1) My resume: courses followed over the curriculum, details on the Master's Thesis (it was for an young graduate position)
2) My expectations of the job: in which specific field I wanted to work and what skills I had that made me qualified for each field
3) My salary expectations: do not hesitate to overshoot a little, especially if you have nice grades
An HR partner contacted me saying the recruitement team forwarded my CV (note: I never applied for any of their positions!). We agree on a date and time for the interview, but he never calls. I emailed to ask if there was some technical problem but never heard back.
