      Principal Associate Data Scientist Interview

      27 Oct 2020
      Anonymous interview candidate
      Richmond, VA
      No offer
      Positive experience
      Average interview

      Application

      I applied through a staffing agency. I interviewed at Capital One (Richmond, VA) in Sept 2020

      Interview

      Interview steps with a phone screen (30 mins). The recruiter was an immensely polite, courteous, and fun person, probably the best I have ever experienced. Then came the technical screen of 60 mins, which was quite easy and smooth. I stumbled at the data the challenge (7 days), which admittedly was my fault as I didn't stick to the questions and failed to address the core last question with confidence. Throughout the entire team was courtious and humble. I didn't go further with them, but this should be a good place to work at with high moral standards.

      Interview questions [4]

      Question 1

      Tell me about yourself? What models and programming languages are you familiar with? Tell me when you managed to solve a dispute with your collegues and managed to get along everyone on a single soloution?
      Answer question

      Question 2

      When to care about bias and how to control variance in your data?
      Answer question

      Question 3

      Case study: How will you allocate resources in a call center? What do we learn from demand and supply? Will go after precission or Recall for such a case as a check on your model?
      1 Answer

      Question 4

      Describe how do you use CNN as your project? How difficult it is to explain the feature importance in deep neural networks.
      Answer question
