Many surveys say that the number one issue facing businesses is finding and keeping . " good employees .

In some cases a simple weighted scoring method is used although the weights are typically not defined using any scientific method and are rarely constant throughout the process. Likewise if a company is using a rating scale and taking averages of all interviewers, it is not easy to baseline on the ranges used by each decision maker.
