Why are reference checks important in the employee selection process?

Reference checks play a crucial role in the employee selection process because they help verify a candidate's skill level and past behaviors. This verification is essential as it provides employers with insights into how a candidate has performed in previous roles, whether they possess the relevant skills needed for the position, and how they interacted with coworkers and management.

By reaching out to former employers or other references, employers can gain a clearer picture of a candidate’s qualifications beyond what is presented on their resume or during the interview. This process can highlight strengths and potential areas of concern, informing hiring decisions and reducing the risk of making a poor hire.

Other options suggest that reference checks are optional or solely limited to certain positions, which does not acknowledge their value across all levels of employment. Salary expectations are typically addressed in a separate part of the hiring process and are not the primary purpose of reference checks. Overall, option B accurately reflects the fundamental purpose and importance of conducting reference checks in the employee selection process.
