3 Rounds - Round 1 (Good) - Data Engineering, PySpark and SQL Basics. Coming from a 6-7 year background questions are easy to answer. Round 2 (Interseting) - Hiring Manager Round. Drill down into intricacies of architectures/project handled. Sample scenarios and supporting answers for choice of design selected. Round 3 (Worst) - CTO round who is so careless about taking an interview but unfortunately he will be the final judge. Stupid questions on DE like explain CDC. How did you handle CDC. He is so nonchalant that he never listens to your answers. If you are so busy why take that additional round. Worst Part - Had to follow up with the HR multiple times to get the feedback. If you are not bothered to hire someone please do not waste his time.
