Never start with a negative attitude towards what you can be offered and what you should be willing to accept.
Negotiate properly but do not undervalue you, try to answer the questions related to your current CTC and expected CTC by showing how much value you can bring in.
If they are not willing you to give the hike as monthly salary then you can ask for one time payments like signing bonus or year end bonuses to get the expected hike.
But most important is how you perform in the interview and remember one thing never make the first offer. Try to get the first offer from them and negotiate from there.
Getting good salaries are all about your negotiation skills.
