Providing salary requirements is a troubling part of the interview process for many job seekers. They don't want to:
A) Price themselves out of the job.
B) Come in too low and leave money on the table.
The solution? Offer a range.
First, Have a 'Walk-Away' Rate
Everyone needs to have a clear number in their mind. That number is the lowest possible amount you'd take to do the job. By that I mean, you'd accept and not be looking for a higher paying job, or have to take another part-time job to cover the bills. Your walk-away rate is what you need to live and be able to do the job without resentment. This varies for everyone.
