Nielsen Research Analyst interview questions

Skills test was 90 minutes and consisted of math and business related questions. Math questions were of high-school level difficulty, while the business/strategy questions were open response and presented a scenario in each. First-round interview had a market-sizing question and basic behavioral questions. Final round was three interviews, each of which had at least one strategy question. No full-out case interviews or anything of that sort. Interviewers were of senior management in the company, but all of them were very laid back and pleasant. Received offer several days later from an HR representative, and a formal letter followed afterwards.
