Applied online via Nielsen website, a couple weeks later HR got in contact with me for an initial phone interview. Phone interview was standard - questions about current role, what do I know about CPG industry, why am I interested in this position & Nielsen etc. At end of phone interview was told to take the online assessment. The assessment was part math (similar to GMAT) and part behavioral. A couple weeks after that I was asked to have another phone interview w/ some members of the Nielsen team I was applying for. Had call w/ 2 members, asked more in depth questions about my resume, how I currently use data, etc. No gotcha questions, just seeing if I was a fit based on previous experience and interest in the role, ability to use data etc. A week or so later, was asked to come in for an in-person interview w/ 2 hiring managers + 2 members of onsite team. Shortly after, was asked to come in for final in-person interview to meet w/ the clients on-site. Total time from application to offer was close to 3 months.
