Don't allow yourself to be badgered by the salary issue:

Even today,it's still not uncommon to hear the old refrain: "Our policy is not to pay a new employee more than X% higher than he/she is currently making." Sorry, that doesn't fly. The real issue, and the only one at stake here, is whether or not your prospective employer is willing to pay WHAT YOU ARE WORTH. And, your worth is a function of the job itself and your capability and willingness to perform it. In most organizations, there are clear parameters for a given job, a range of salary that is adjustable depending upon the market and the applicant's experience. In most cases, unless you are very good, you will have to work within those limits. But, within the limits, what you are worth is a matter of mutual agreement based on your own knowledge of your worth and your ability to convince those interviewing you. So, to sum it up: Know the range of compensation for the job you're seeking, make your own realistic determination of what you're worth, and then be prepared to stand your ground.
