One might think lousy economic conditions would make companies more selective during recruiting. Instead, employers appear content to endure poor performers rather than take a chance on unknown commodities, a new survey suggests. Caliper, a management consulting firm in Princeton, New Jersey, finds that nearly seven in 10 employers find it easier to manage “the devil they know” than to take risks on hiring unknown new people. A mere 31 percent say the opposite, according to Caliper’s survey of 190 U.S. hiring managers from various industries. Caliper says the results underscore employers’ need to move beyond surface qualifications and rely more on behavioral interviews and personality assessments when making hiring decisions.
