So far I have only been to their first interview. It was purely a get to know interview with their HR manager. The lady was very professional and was interested in my previous experience in the field. Common questions were asked about why I quit previous jobs and how do I see myself in ACNielsen. Unforunately, I was not invited to a second interviw, but as far as I understand it was going to be a skills test and there is also a presentation somewhere along the way.
