It started with first round as HR round -> Assessment test (Open book and internet) like a case study which may take 4-5 hrs. Start considered as the time you receive the test question on email and the end time will be when you send it back with a solution. Be precise, detailed and you will get the scores and then they will evaluate and select accordingly. Most probably, the next round would have been the main round with the Director. Overall, it was a professional and smooth experience.
