As millennials continue to make up a larger share of today's work force, employers should incorporate this diverse demographic into their organizations, but identifying the right millennial job candidates takes a different approach from traditional recruiting, says Susan Vitale, chief marketing officer of iCIMS, a provider of talent acquisition software solutions that has had success recruiting and retaining millennial employees.

When it comes to recruiting millennials – or any specific demographic for that matter – human resources professionals should look at the process from a marketing angle, Vitale says. Successful marketing highly depends on the right medium of communication, and this varies based on the audience. What may be effective for one demographic isn't always the best method for others.

"More organizations are recognizing that recruitment in HR needs to wear a bit of a marketing hat," Vitale says. "Just like if your organization is marketing a product or a service, you need to ensure you're reaching your different audiences in a way they prefer to communicate. The same thing goes with targeting millennials. It's not a complete upheaval of the existing recruitment advertising strategies; it's making sure you're not leaving them out of the loop or completely ignoring them. Recruiting is not a one-size-fits-all strategy."
