An automatic sorting algorithmsupervised by a junior recruiter whittles down the submittedrésumés to an initial shortlist. All résumés in this shortlist gothrough the next three steps.

This takes about8 minutes per résumé. (2) Resource-type "technical person" (usuallywith some help from the group that has posted the position) checksthe résumé for evidence of technical skills and ranks theshortlisted candidates on a technical scale (technical ranking).This takes about 5 minutes per résumé.
