In some cases, the hiring manager raises the question during the interview, therefore disclosing your past salary is personal choice. If your past salary is lower than what the company has in mind for the position, the employer might think you lack the necessary skills and may disqualify you if you state your previous salary. On the other hand, if you give a higher amount , the employer may rule you out, thinking you will not be interested in lower salary. In reality, potential employers do not need your salary history to employ you. Many do it to pressure candidates into giving up confidential information, which gives them the upper hand during salary negotiations.
Decline to the salary question. You can use diplomacy to try to get around questions about your past salary. It is best to say you would prefer to know more about the position before discussing compensation. In addition, acknowledge that you are certain both sides can arrive at a mutually beneficial salary after the interview. Then, explain that you would be happy to demonstrate what you can do for the company.
Example, Look at this conversation between a Job seeker and a Responder
Job seeker: I went to a job interview today and they asked me what my previous salary was, should I tell them?
Responder: The short answer is no. If your previous salary was low, they will just use it to low ball you. In some cases that question is actually illegal.
Job seeker: So how do I respond without being rude?
Responder: Say something like, I would prefer not to disclose it. I believe we can negotiate a fair compensation based on my skills and the value that I can bring to this company.
Job seeker: And what if they still keep pushing me to tell them?
Responder: In case, turn it back on them, ask them what is the salary range for this position? I will be happy to consider all reasonable offers.
Job seeker: Thank you.
