I have not completed the interview process as of yet. At this point, I have had a phone screening and an analytical assessment. The process began when I was contacted for a phone interview via email roughly 5 days after applying online. I had the phone interview a week later, which consisted of basic interview questions. It was mainly to set up the standard analytical assessment, which I took later that week. The analytical assessment was not too difficult, as it consisted of probability, statistics, and case studies. The questions were worded as if they were intending to confuse you, so make sure to read each question thoroughly and answer what they're asking you. I am awaiting my results on the assessment, which I took just 2 days ago. I am expecting to hear back from Nielsen this week.
