I applied through an employee referral. The process took 4 weeks. I interviewed at Nielsen (New York, NY) in May 2015
Interview
Connected to the SVP on LinkedIn and asked about any suitable positions based on my background and experience. He referred me to a HR who interviewed me for the specific role they were hiring for. Progressed to the next stage where the VP of the team interviewed. Questions about the projects I had worked on, what my role was, why I was looking to move from my current role, and if I had any background in probability and statistics. After a week, received a request to come onsite for more interviews. Since I was located in a different state, they decided to conduct the interviews via Skype. Had 4 more rounds, with 2 VPs, 1 Director and 1 Sr. Research Scientist. All of them questioned me about the projects I worked on, what tools I used, my background in Analytics. Since I had a couple of years experience in this area, the questions were focused on the different types of projects and my role in them. The Research Scientist asked me some questions on R and the Director asked me some technical questions about clustering, missing value imputation. Overall very nice experience. Received an offer about a week after the last interviews.
Interview questions [1]
Question 1
How would you get all the unique values from an attribute in R?
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.
I applied online. The process took 1 week. I interviewed at Nielsen (Bengaluru) in Jan 2025
Interview
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!
