After you post your job requisition, Brainhunter's job-match engine immediately begins compiling a list of candidates (the A-List) that meet your requirements. Every time a new candidate is added to the A-List, you are sent a "new candidate email alert". A-List candidates meet the Match Threshold that you set. If desired, you can click the B-List number link to find out why specific candidates did not make the A-List. B-List candidates do not meet the Match Threshold that you set. Often B-List candidates are still worth looking at.
