Nielsen had posted a job posting on my university job board so I got the first-round interview from that. They asked me to allocate 2 hours for the interview, but be prepared for longer, especially if they're running late. First I had a half-hour behavioral interview, which they sprinkled throughout with small case questions, like the Listerine question another reviewer had. I was a bit thrown off by them, so just be prepared to answer. I spent the next 1.5 hours taking an analytical assessment, which I prepared for by spending an hour practicing GMAT questions. I finished early, which I think is a good indicator of how helpful doing practice math problems was. The whole point of practicing was to get myself familiarized with basic probability, percentages, etc. again. The test consisted of 10 business word problems and 2 essay questions. I just got called in for an on-site interview so I'm guessing I did alright.

Behavioral questions in interview after having taken an online skills test with timed brain teasers. The night before the interview, there was a pre-interview social even in which I met both my interviewers.
