It was a 4 hour long interview with 4 individuals. Each round or section took roughly around an hour. Each round starts with an interactive test/exercise and then is followed by some behavioral questions. 2 rounds are very simple. They basically come up a use case situation and wants to you go through it with them. In these 2 rounds they're basically trying to see whether you can work along with them and how apt you are coming with business solution ideas. The last 2 rounds are case rounds. One case interview is going to be most likely a cost-benefit analysis and the other one a more quant heavy problem or case. None of them requires sophisticated arithmetic skills. GMAt math standard is enough.

Three round interviews, and the final round will have three interviewers coming one by one. Handwritten codes are required, and also prepare statistics questions. Interviewers are nice and are really supportive. Technical questions are more than behavioral questions.
