2 rounds
1 -> telephone interview with manager, ask questions related to my CV
I waited for 1 week to get into the second round
2-> case study interview with skype
the case interview was not given in advance.
The question I had is -> we are going to launch a product, please give your opinion whether we should launch it or not. you can ask any questions that help you to make the decision. (this type of question is similar to those you will have when interviewing a consulting firm)
