      Data Scientist Interview

      25 Apr 2022
      Anonymous interview candidate
      Dallas, TX
      No offer
      Neutral experience
      Average interview

      Application

      I applied online. The process took 2 weeks. I interviewed at Certegy (Dallas, TX) in Apr 2022

      Interview

      Interviewer explained the company and position, then asked a series of pretty data scientist interview questions. Things about different metrics, types of models, SQL joins, etc. Then he went through a fairly simple business case that involved several calculations about credit card balances, usage fees, and interest from the financial institution standpoint. It felt more like a math or finance test than a data scientist interview up until the last question, which was if I wanted to test different strategies how I would go about doing so.

      Question 1

      What is the difference between a random forest and a gradient boosted decision tree?
