I would be joining also in a couple of weeks, as I understand the housing is very expensive and dificult to get. The company could provide you with a 2 bedroom apartment but if your family is to big that does'nt works. So plan to expend some money in rent. Only to overnights in India as far as I know, but that is going to chenge in the next 2 years.
Hope to meet you there and best of lucks.
