When to Check
Checking references is usually done at or near the end of the interview process. Too often it is not done well or thoroughly enough. When you have reached the stage in which you are close to making a decision on a candidate, ask him or her to supply up to five references, at least one reference from every job that he or she has held. In addition to professional references, the candidate may offer a reference letter from a former professor or colleague.
Who Does It
If your company is large enough to have a professional human resources specialist, he or she should do the reference checking. By the final stage, you, the hiring manager, should call at least one reference if you are the direct supervisor. Reference checking should not be done in writing; you will get little in the way of verification. All you probably will get is name, rank, and serial number. Because of the potential liability, most companies are reluctant to put anything in writing.
Checking by Phone
When you call a reference, prepare to spend some time on the phone. Build rapport, and get him or her to feel comfortable with you. Assure the person that everything will be held in the strictest confidence and that you want to make sure you are doing right by the candidate and your company.
