When you have found a candidate for a position at your place of business, it is a good rule of thumb to then send a Job Rejection Letter to each candidate who was interviewed but not chosen. Check out our library below to download Job Rejection Letter templates and samples. Alternate Names: Job Application Rejection Letter; Job Rejection Email; Candidate Rejection Email. A Job Application Rejection Letter is used to inform an interested applicant that they have not been chosen for the role, as well as to save the employer time from having to answer questions from applicants when the role has already been filled. Sending out a Job Rejection Letter response will also show you are a company of good character that follows up with interviewers, which in turn can mean more positive reviews of your company for future applicants who may be interested in applying.
