Talent shortage is the biggest hiring challenge today. In a recent Harris Poll of 515 U.S. human resources and business managers conducted for Glassdoor, 48 percent of respondents said they are unable to find enough qualified candidates to fill open positions, and 26 percent of respondents anticipate this to become a larger problem in the coming months.1 In the face of this challenge, many employers are devoting even more resources to talent searches, assuming that finding the perfect candidate will deliver better ROI than developing existing the skills of existing employees.
