Primero telefónicamente se comunicaron y tuvimos una charla en inglés. Luego presencial con alguien de rrhh y finalmente con el líder de equipo del proyecto. En los tres casos tuve la reunión en español y en ingles para conocer mi nivel de habla y lisening.
Interview was of three rounds. First round coding and multiple choice based questions. Second round was technical interview and third round was managerial. All the rounds were pretty smooth and the process was quite transparent.

Hi everyone,
I recently gave the Nielsen Data Scientist test through HireVue. The questions were simple, covering Python, SQL, and aptitude. However, I strongly recommend Nielsen to not to use HireVue for the hiring process. The section-wise timing was uncomfortable and affected overall performance of candidates.
I suggest Nielsen consider using a single timing for the entire test instead of separate timings for sections. This will let candidates show their strengths and weaknesses better, helping to select the best team for higher company performance. By clustering candidates performance, you can create a team of candidates with different expertise, such as one excelling in aptitude, another in ML, and others in statistics. This way, you can build a balanced and highly skilled team.
Nielsen is a great place to work, but improving the test process would make it even better.
Thank you!
