      Data Engineer Interview

      5 Jan 2022
      Anonymous interview candidate
      London, England
      No offer
      Negative experience
      Average interview

      Application

      I applied through a recruiter. I interviewed at Profusion (London, England) in Sept 2021

      Interview

      - A recruiter approached me for a data engineer opportunity in Profusion. - I met a Lead and Senior Engineer and was asked a couple of SQL, Python and Cloud questions. - I was asked to do a technical test in Python (using an existing API for which I would have to read documentation) and to write around 10 SQL queries that solve different issues. I didn't do great in the first interview, but they still asked me to do the technical test, which I aced. I sent them the results. They never responded or shared feedback. Complete waste of time!

      Interview questions [1]

      Question 1

      Q: - GROUPBY - KEYS in SQL - Advantages and Disadvantages in Serverless - How do you know you successfully transfered all data?
