Nielsen Data Scientist interview experience

The first round was coding combined with multiple-choice questions, and the focus stayed in a technical lane.

The second round was a more technical deep dive, and the third round shifted toward managerial topics. What I remember most is how easy it felt to follow the flow—nothing felt hidden, and the whole thing stayed organized.

In the end, I didn’t get an offer, but the experience itself was described as positive by me during the process. The overall difficulty landed in the average range for what I was asked.
