While it is inappropriate to discuss salary until an
offer of employment has been made, it may come up and you should be
ready.
You should be prepared to state the amount you feel you deserve.
Do your
homework
Find out the salary range for the job before your interview. Consult
books, people in the field or a career counseling of placement office.

Be realistic
Take into account that salaries vary according to region, size of
the company and your qualifications. Also, salary may not be the most
important consideration. But don't undersell yourself either, asking
for too little money can hurt your chances as much as asking for too
much.
