There were 4 rounds of interviews, written test (text mining using any tools, I used R studio). Panel round with VP, Principle analyst and Sr specialist-seem to have very little knowledge) - they asked my approach to solve the written test and normal questions from my CV, and then final f2f round with the director based in gurgaon office (it took 1+ month to get it scheduled) and it was a pathetic interview as the director was not at all interested in taking interview and kept on looking at the laptop to search for the interview questions to be asked and she was yawning the whole time. I found it very rude. And 4th round was the HR one.
