And it's not just a first-day mistake, it's an ongoing problem.

People in the office try to give that intern less-than-subtle hints — like when the boss pulled out an extra tie and demanded that intern put it on. Or when the intern supervisor asked that intern not to be in the group photo for the Web site. Or when all the other interns staged an intervention at happy hour. Or when that intern suddenly got a horrible nickname like, "The Skintern."

About #THATintern: Every intern class has “that intern” — as in,“Don’t be that intern.” Each day I introduce you to one of them. Share your ideas on Twitter using the hashtag #THATintern. And check out our Intern City page, too.
