A job application letter is a formal letter sent by a candidate to apply for a specific job opening. It typically accompanies a resume and serves as an introduction to the applicant’s qualifications, skills, and interest in the position. The letter highlights the candidate’s relevant experience, explains why they are a good fit for the job, and expresses enthusiasm for the opportunity. It may also mention how the applicant learned about the position or company. A well-crafted job application letter serves to catch the employer's attention and encourage them to review the applicant’s resume, increasing the chances of being selected for an interview.
