And for those of you who do not have experience in sales, one piece of warning. While it is helpful to think of the interview as a sales call, do be careful not to overdo it — to not oversell yourself to the point where you actually turn the interviewer off about your candidacy. You need to walk the line between being too modest about your accomplishments and fit with the organization and talking too much about yourself.
Finally, always remember that the interview really is a conversation between two parties who are both trying to showcase their best points. Your goal is to leave the interview knowing you did your best to sell your unique mix of skills and accomplishments while overcoming any objections raised by the interviewer.
