Question

Quizplus · Accepted Answer

A reference check from an investigative agency would be the most thorough as they have the resources and expertise to thoroughly research a candidate's background and employment history. They can also uncover any potential red flags or discrepancies in the candidate's work history. References from former employers or colleagues may be biased or limited in their knowledge of the candidate's work performance. A letter of recommendation is also subject to bias and may not provide a comprehensive assessment of the candidate's qualifications.
