The New York Times recently interviewed Janna Eggers, the chief executive of Spreadshirt, a maker of personalized clothing. She is a bit of a hyper-achiever, and I would not recommend her sleeping habits! But, there was one precious nugget of wisdom she passed along when asked about how she hires staff.

I’m also going to see how they treat the receptionist. I always get feedback from them. I’ll want to know if someone comes in and if they weren’t polite, if they didn’t say, “Hello,” or ask them how they were. It’s really important to me.

Would the receptionist give you a good reference?
