      Application

      I applied through a recruiter. I interviewed at Nielsen (New York, NY) in Apr 2021

      Interview

      Met with the data science recruiter and the director of the team. Had a technical interview with the director and the staff data scientist on the team. Had a group call with some members of the team. Met with the director's boss.

      Interview questions [1]

      Question 1

      Technical test was a live, timed test where you could use any resources you needed to. It involved a series of short, straightforward Python tasks involving lists/dictionaries followed by a pandas data transformation task in a Google Colab notebook. Then I was asked to analyze a regression task output and any potential issues, followed by some general questions like, what are the pros/cons of random forests vs. gradient boosted forests; if you were trying to predict XYZ, what would you consider using, etc. Most of the other questions were around my past work or other case type questions - how would you solve this or go about doing this?
