The Nielsen Company has an extremely competitive and demanding interview process. In my experience it had four components: 1) Preliminary Phone Screen 2) Math Skills/ Business Acumen Written Exam 3) 3 1:1 Interviews 4) 3 more 1:1 Interviews Preliminary Phone Screen - in this segment, I was introduced to my recruiter. She was extremely nice and helpful throughout the process. The screen consisted of general questions regarding my education, my background, some brief leadership questions, and my knowledge of the company. It was relatively easy. Written Exam - This exam was EXTREMELY hard. I took it on site, was given a calculator and scrap paper and roughly 2 hours. The questions are similar to GMAT questions but each question consists of at least 3 or 4 parts. They are difficult but if you don't panic and try to reason through the questions you can solve them. Make sure you are strong with WEIGHTED AVERAGES questions, as well as basic algebra, and MGMT ACCOUNTING questions involving Break Even Points, Fixed Costs and Variable Costs etc. But especially weighted averages. The second part of the exam are written case study questions. You need a fundamental understanding of how to approach case studies to excel here. I strongly recommend Cosentino's Case In Point book to acquire the skills necessary for case studies. 1:1 Interviews - The interviews were all extremely pleasant, and I could tell that I would enjoy working with my colleagues. The questions were behavioral ("leadership", "time you failed", "time you disagreed with a colleague," etc.). I also had a case study on each interview so roughly 6 case studies. They were mainly New Product Development cases, Industry Analysis Cases, Growth Strategy Cases, some Market sizing and some simple Random Questions ("How many quarters will it take to get to the top of the empire state building?") The case studies were interesting and fun to discuss. After my second round of interviews I received a phone call and a verbal offer. I was ecstatic! This is a great company to work for!!!!!
