Study says that this Commonly-Used Interview Screening Tactic Actually has 'No Value'

"Clearly, a more nuanced understanding of the applicant as well as his or her personality, aptitudes, work style, technical skills and fit for the position are necessary to make more informed recruiting decisions."

The chart below shows that those who perpetually changed jobs and those who didn't change as often have similar chances — only an eleven day difference — of staying at their current jobs for longer periods of time. The different colors represent how many jobs a person's held in the last five years:
