In fact, you should avoid stating your current or desired salary when you interview, as well.
I've been in the job market for--well, let's just say a hell of a long time--and have made a number of job changes, so I know what I'm talking about. The best pay increase I ever got in changing jobs was when I refused to
ever tell my prospective employer what I was currently making. I did finally state a compensation figure as a combination of salary + benefits, which sounded like I was doing a hell of a lot better than I was. They ended up offering me the job at a 33% salary increase, PLUS excellent benefits! (Of course that job only lasted a year, but the next job I took paid a little more than that, so it was still good.)
from Focus magazine, January 5, 1983What do you feel this position should pay?Salary is a delicate topic. We suggest that you defer tying yourself to a precise figure for as long as you can do so politely. You might say, "I understand that the range for this job is between $______ and $______. That seems appropriate for the job as I understand it." You might answer the question with a question: "Perhaps you can help me on this one. Can you tell me if there is a range for similar jobs in the organization?"
If you are asked the question during an initial screening interview, you might say that you feel you need to know more about the position's responsibilities before you could give a meaningful answer to that question. Here, too, either by asking the interviewer or search executive (if one is involved), or in research done as part of your homework, you can try to find out whether there is a salary grade attached to the job. If there is, and if you can live with it, say that the range seems right to you.
...Don't sell yourself short, but continue to stress the fact that the job itself is the most important thing in your mind. The interviewer may be trying to determine just how much you want the job. Don't leave the impression that money is the only thing that is important to you. Link questions of salary to the work itself.
But whenever possible, say as little as you can about salary until you reach the "final" stage of the interview process. At that point, you know that the company is genuinely interested in you and that it is likely to be flexible in salary negotiations.
I've also read the advice, "Make them gasp" if you just can't get out of quoting a figure first. If you're currently making $35,000 and you want to make $45k, tell them you want $60k. Then, if they're interested, they'll offer you as much as they can. If you scare them off, no sweat--you didn't want to work for them anyway. (Not always true, of course; you have to weigh each opportunity's pros and cons individually.)
