It depends on your industry, experience, and demand for your services. Since you don’t give any details I can only offer general suggestions. You need to address these questions, beforehand.
What value do you bring to the job?
What is your experience?
What is your salary history?
What is the value of the job’s benefits package? That is part of your salary.
And a few points to consider:
Don’t negotiate salary until you receive a job offer.
Make sure the person interviewing you has the authority to make an offer.
Ask questions, don’t make demands.
