At first, the HR called and there was an initial HR screening. Next, the interview was with the manager of the company who interviewed me based on SQL, and Economics and also asked what type of work I do in Excel. The third round was with the director of the company who mainly asked personal questions. The fourth and the fifth round were with the client where two people separately interviewed based upon my previous work experience. The sixth round was an excel and a SQL test.
Finally, the HR called to say another candidate was selected for the interview.
