First technical round: Coding—Python, PySpark, SQL one question each Second technical round was really weird. The interviewer didn’t switch on her camera. She asked no questions about my resume. She asked me Python, PySpark, SQL questions. (Really easy like window functions and lazy evaluation, wide vs narrow transformation.) No followup questions. I answered all of it and then she ended the call twenty minutes early. Seemed disinterested and eager to get it done with.

Once you are pre-screened, you get a codesignal test. Once you solve at least 2 out of 4, you are invited to a 1st round interview where they ask you basic sql and python questions. 2nd Round - my interviewer was very condescending and got offended by my definition of a data engineer. Their communication style included remarks that felt condescending, such as implying a question was "sixth-grade level," despite it being a specific Python trick. This made the interaction quite unpleasant and difficult.
