The interview process had 5 rounds. The first round focused on Python coding, SQL queries, Spark optimization, and streaming concepts. The second round was more about architecture, including project ETL architecture and some design questions. Round 3 was a managerial round where they asked about project impact on business and ETL design for banking. Round 4 was with the Team Head, covering general questions. The final round, Round 5, was with the HRBP and was described as the hardest, where HR really digs into all aspects, so it's important to be well-prepared for scenario-based questions and every word you say. Overall, it was a very challenging yet fun experience.

We had on-campus recruitment, with 3 rounds in total. The first round was an aptitude test, which was super competitive. Only 14 out of 150 students made it based on accuracy and speed. Then, the second round was a technical interview, and on the same day, those who passed had the third round, which was a mix of HR and Technical.

Overall, my interview experience with TechCo Innovations was rigorous but well-organized. The company's representatives were professional and respectful throughout the process. I appreciated that they placed a strong emphasis on both technical skills and cultural fit, which showed that they value a well-rounded candidate. As of my last communication with TechCo, I am awaiting a final decision. Regardless of the outcome, this interview experience has been valuable in enhancing my skills and providing insights into the kind of opportunities and challenges that TechCo offers. I look forward to continuing my job search with enthusiasm and confidence gained from this experience.
