Note that whenever you are going for an interview, this question may be asked. Before going, try to find out what the average salary for someone holding that position in that industry is paid. This would help prepare you for what is in front of you.

Do not forget that this is only an interview and you haven’t been offered the job, so do not go on negotiating. Just state something within the range you have researched and move on. Whatever you do, do not sell yourself short.
