      ETL Developer Interview

      Oct 7, 2025
      Anonymous interview candidate
      Chennai
      No offer
      Negative experience
      Easy interview

      Application

      I applied online. The process took 1+ week. I interviewed at Tag (Chennai) in Aug 2025

      Interview

      Round 1 & 2: Technical discussions related to ETL concepts, SQL, and project experience. Both rounds went smoothly, and I received positive feedback from the interviewers. Round 3: Final client interview, where the client appreciated my answers and gave positive comments. However, after the round, HR informed me that the client did not move forward with my profile, without giving any proper reason. The overall process lacked transparency after the final round.

      Interview questions [1]

      Question 1

      They asked me to explain the complete ETL process in my project — including data extraction, transformation, loading, and error handling mechanisms used.
