First clarify, whether they are going to give you HRA or they are going to give you a accomodation.

In case they say that they are giving you HRA then know that a decnet 1BHK will cost you 4K upward, depending on the area.

So make sure that when they give you the salary you look at the salary and the HRA differently and do not mix them together, because unlike in your home country you will have to use your HRA here coz you do not have a house here.

And make sure what salary they are paying you, don't get sold for the idea of a 'attractive salary', what may be attractive for them may not be attrictive to you.
