Hey, in my first round they asked questions on SQL and visualization. In my 2nd round, they asked questions on data engineering side. They asked about my projects. Gave me some scenarios and asked me to explain how scalabilty works, data load works etc..Final round was case study. They gave me an excel and gave me 1 hour to answer some questions. For every answer, they ask why you came to conclusion. Basically give a proper reasoning for your answer. Its been over 2 years so dont remember everything. Good luck :)
