There are several reasons why a Resume may get rejected, some common reasons include a lack of relevance to the job, poor presentation, errors, lack of achievements, inappropriate photos,unexplained gaps in employment history or too much personal information. It's also important to note that many employers use Applicant Tracking Systems (ATS) to screen Resumes before they are even seen by human eyes. ATS software scans Resumes for relevant keywords and phrases, and Resumes that do not contain the right keywords or have formatting issues may be automatically rejected. To avoid rejection by ATS, job seekers should tailor their Resume to the specific job they are applying for, use keywords and phrases relevant to the job, and avoid using fancy formatting or graphics that may confuse the software. Seeking feedback from a professional Resume writing service can also help job seekers to optimize their Resume for both human and software screening, and help avoid rejection.
