The process took 2 months. I interviewed at Nielsen (Milán) in Apr 2011
Interview
So far had the skills test, you can prepare perfectly for it reading what other people posted in this website: gmat, probability, basic percentage, basic profits=revenues-costs. Don't expect it to be too easy, time is critical and the two essays you have to write after the 10 math questions are very articulated and time consuming. Only 10 % passes and I can tell you everyone completes the test. It's all about how precise you are and complete in your answers as well as how good your english is I guess. I always specified the assumptions upon which my answer was built and I think that helped.
Second step is a normal behavioral type of interview. If you are applying for Nielsen Bases you'd better know what Nielsen Bases is, not like I did. Waiting for a third step which is two 1:1 interviews.
it was just regular interview process, asking about the past experience, interest in the field. Ask for excel skills. I interviewed for the technology department, so I was asked about my interest in technology and some related questions--trend technology
Was given a task and interview. Expect a brief based on a supplied dataset, then a presentation in person. Good process, straightforward, would recommend. Need to fill word limit to submit this review.
