Even in a good hiring market, it’s often difficult to sort out good job candidates from great ones. Here are a few things you might consider in making your next hire.

Five Things to Look for in Hiring Great Employees

1. They overshoot job descriptions.

Listen for stories about how they’ve stepped out of their job description to do whatever it takes to make a customer happy.

2. They’re not run of the mill.

Don’t misread unusual personalities as eccentric, but consider that they might just be creative problem solvers who aren’t afraid to question the way things are being done.

3. They work hard and play hard.

And—most importantly—they’re able to flip the switch between the two appropriately.

4. They aren’t intimidated by the success of others.

In fact, they delight in their team members’ successes as well as their own.

5. They love a challenge.

Listen for the drive that indicates they believe they can make a difference not only in their workgroup and organization, but in the world as a whole.
