Write the ranking number on the back of each resume and after you select the final candidate turn over the resume and see what number is on the back. In one test the candidate selected was No. 75 out of 100. Often the reverse is true. Identify the top performers that have been hired during the last three years and see what they have in common. Don't be surprised if the top performers don't have great grades, perfect references, or a degree from a top school.
Managers often assume that all sources are equal in producing long tenure hires.
Identify the top performers that have remained for over four years. Check to see which sources produce those that stay the longest or shortest. One study found that the primary reason for rejecting offers was how poorly candidates were treated during the hiring process. Ask them to assess courteousness, responsiveness and the accuracy of the information given out. Don't be surprised if sometimes a resume is accepted with a Caucasian male's name, while other times it is rejected with a minority or a woman's name.
