Q. Smith & Nephew Don Joy, Inc., is a small but fast-growing manufacturer of medical devices in the north end of San Diego County. Because of the recent downsizing of Southern California's aerospace and defence industries, each job opening at Don Joy draws five times more applications than it did just a few years ago. Explain however, selective layoffs made during the downsizings and the need for people to seek new career paths has created a glut of less-than-qualified applicants. Illustrate what selection tool(s) can Don Joy use to get the most qualified employees from its huge pool of applicants? In general, which selection tool(s) do you think are the best predictors of job performance?
