Interview Questions

Interviewers expect a candidate for employment to be able to provide the details of their compensation history. Be prepared to tell the interviewer how much you earned at each of your prior positions.

Make sure that what you tell the interviewer matches what you listed on your job application. Refresh your memory prior to the interview by reviewing your salary history, so, you can speak in detail and accurately. Don't exaggerate or inflate your earnings. Many employers will check references and confirm your salary history prior to making a job offer. A discrepancy between what you reported and what the employer says could knock you out of contention for the job.
