      Data Scientist Interview

      Mar 1, 2026
      Anonymous Interview Candidate
      London, England
      No offer
      Negative experience
      Easy interview

      Application

      I applied through other source. I interviewed at Stream (London, England) in Apr 2025

      Interview

      Screening plus 3 rounds. First round was a SQL test. Second round was a Python test. Final round was a general chat with the department lead (C-Suite). At the end, suddenly the co-founder wanted to have a chat, and the motivation was not made clear. It turned out that he was interested in getting contractors to fulfill the role instead, so despite having passed the process, the role was discontinued.

      Interview questions [1]

      Question 1

      SQL questions to calculate aggregates and do joins. Python Pandas questions ( aggregates, window functions, basic statistics)

      Average interview

      Application

      I applied online. I interviewed at Stream (London, England) in Mar 2025

      Interview

      It was horrible, the interviewer was distracted and did not communicate clearly. It was unprofessional, careless and did not value the effort or time of the interviewee. Big no to management.

      Question 1

      Technical round full of query and visualisation
