A reference check is a process used by employers to verify the qualifications and character of a job candidate. During this process, the employer contacts individuals who can provide insights about the candidate's work history, skills, and behavior. These individuals are often previous employers, colleagues, or mentors who can share valuable information about the candidate's performance and reliability. The goal of a reference check is to ensure that the candidate is a good fit for the position and the company culture. It helps employers make informed hiring decisions by confirming the details provided in the candidate's resume and during the interview process.
