      Principal Data Engineer Interview

      25 Nov 2022
      Anonymous interview candidate
      London, England
      No offer
      Negative experience
      Difficult interview

      Application

      I applied through a recruiter. The process took 3 weeks. I interviewed at Contino (London, England) in Nov 2022

      Interview

      All very open and transparent. They will give you the feedback from interviwers as they said it/wrote it. There is a first interview with a technical person, more to evaluate your area of expertise . Then one interview (or 2) that are: - Culture fit - Technical interview In the technical interview you will be told that you dont have to write any code, but you will get obscure questions around Python / git / SQL (if you are applying for Analytics). In the end you might get a no, if you dont "fit the profile" and all it takes is one person dont liking the way you look/speak/act to get a no. Just look at the pictures in their website. They are NOT inclusive.

      Interview questions [4]

      Question 1

      SQL Imagine you want to make some changes to table A, without actually changing table A. How do you do it ?
      1 Answer

      Question 2

      SQL (follow up) Now imagine that you have a user that is "always" accessing table A, but you need to move the changes (in 10000 rows) from the temp table into table A without the user being affected. How would you do that ?
      1 Answer

      Question 3

      Python: Have you ever used a context manager ?
      1 Answer

      Question 4

      GIT: I have made 2 commits, but I want to merge both commits as just one to the origin branch. How do I do that ?
