Nielsen ARC Analyst interview questions

I applied through the the online job portal, then after a week got mail a for the aptitude test. Aptitude test had three sections quant based, case study, a report writing and a grammar test.. The level of difficulty was high for quant as compared to other section. One really has to manage time to be able to attempt all those section

4 rounds through campus placement ....1st Aptitude test...fairly difficult .... includes questions from logic & quants .... also from english vocabulary & letter writing or paragraph summarizing...then hr interview ....technical interview...then interview with VP or some more higher level employee...questions become more general towards final rounds...
