Pre-employment screening involves investigating potential employees' backgrounds to hire quality applicants. This leads to higher productivity, quality, and lower turnover. Accurate screening helps organizations hire genuine employees, protects current staff, and increases productivity while reducing costs. However, most employers spend more on other resources than screening, despite 30-80% of resumes containing lies. Hiring the wrong person may cost more than their annual salary. Screening includes verifying education, employment history, references, social media, records, and medical information. Employers can use third parties and consent is required, with candidates receiving summaries.
