Hiring strategies

A new study in JSTAT introduces a hiring strategy model that suggests dividing candidates into two groups: those to be evaluated and rejected upfront, and those to be selected based on their performance relative to previous hires. The optimal approach depends on the company's objective, balancing quality and speed.
