Selection process includes a first phone interview with HR, three addiction phone interviews with upper-management level (interviewers were from different locations and teams), and three face-to-face interviews with team and manager. From my experience, HR people were great! They were nice, outgoing and very flexible. Provided guidance about process and were super helpful. Nielsen seems to have a great culture and I really had positive experiences with everyone I met. Didn't make the last interview but process was a good experience!
