Boomerang Employees

Credit Suisse says the network also helps it spot new business opportunities as ex-employees move to client firms, giving the bank an "in" when pitching projects.

Such sites let a firm focus on ex-employees with the most potential, rather than spread itself thin among former staffers with little promise, says Christopher Collins, an associate professor of human-resource management at Cornell University's School of Industrial and Labor Relations.

Even the most rigorous interview process and entrance exams can only provide "a very small snapshot of how a person performs in the organization," says Mr. Collins, while actual experience at the company can speak volumes.
