For freshers:

You are very lucky that you are sitting in an interview……you can’t be demanding. Your answer should be, sir as per company policy whatever package would be offered I’ll accept that. But this is a very casual answer.

Your answer should be something like: “Sir, as you know I am a fresher and the only thing I can expect at this point of time is that I should get a job in a prestigious company like yours. Of course every one works for money I would be expecting something which is sufficient to make my living in a city and I should be able to support my family a bit.
