What does a reference determine in the hiring process?

The correct choice highlights that a reference provides external validation of a candidate's qualifications. In the hiring process, references are typically individuals who can confirm the skills, experience, and work ethic of a candidate based on their past performance. Employers often contact references to gather insights that may not be immediately evident from resumes or interviews. This external validation helps employers make informed decisions about whether a candidate is suitable for the role they are hiring for.

The other options do not capture the primary purpose of references. For instance, job titles are relevant but do not encompass the broader evaluation of a candidate's abilities and character. A candidate's salary expectation pertains to negotiations and is not influenced by references. The number of interviews conducted may imply a thorough search but does not directly relate to the role of references in confirming qualifications. Overall, the significance of references is rooted in the assurance they provide about a candidate's past performance and fit for the new position.
