An Applicant Rejection Letter is a letter informing a job applicant that he/she was not chosen for a particular position. A job applicant may not necessarily be rejected by letter. Very often, no rejection at all is made, but a simple understanding that a drop in communications is equivalent to rejection. Occasionally, a job interviewee will be rejected on the spot after an interview, rather than notified by mail. In addition, email is becoming an increasingly common way to reject job applicants.
However, it is a good idea for a company to have a practice of sending out these types of letters because a) it produces some goodwill between the rejected applicant and the company-if another job comes up, the rejected applicant will be more likely to apply if in prior situations, he/she had been treated with respect by the company; and b) by establishing a rejection procedure and record, the company may be able to protect itself from some claims by the rejected applicants.
