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!
