正确答案：Part (c)There can be significant problems with references, these include the fact that most referees are well known to the applicant andhesitate to say anything critical. However, the more skilful reference reader learns to look for what is conspicuous by omissionalthough there is always the risk that the writer merely forgot.Often there are glowing tributes designed to aid the candidate on their way and some can be too ambiguous to be useful.It is also important to note that references are poor predictors of future performance, are time consuming for the referee and thesubsequent reader. A particular problem is that employers who want to rid themselves of unsatisfactory employees could write anenthusiastic reference, or at best one which leaves a lot unsaid.However, care should be taken when providing references. Potentially, there can be legal consequences if a reference is misleadingor misrepresents the person for whom the reference is provided.In addition, problems can arise when references are sought too early in the recruitment process and therefore breach confidentiality.
