Very redundant, inefficient. There are 5 rounds, out of which 3 rounds can be avoided if the concerned people are there in one call, instead of saying the same things for 3 different people in 3 different calls. In my opinion having an extensive 5 round interview is not worth it for the company.

There are six interview rounds for the Market Intelligence Team, covering resume discussions, prior project experience, guess-estimate problem solving, and a case interview round, thoroughly testing analytical, problem-solving, and strategic thinking skills
