 Just a few minutes away from the Dulles International Airport, crowds of hundreds gathered last week, all waiting outside in a long line to get their security and get started with DHS. There are long lines. It is hot today. There's a little bit of cloud cover. Sharon Wong is DHS's chief employee experience officer. At the event, Wong worked all day long, speaking to candidates who were waiting to get into the building. She also helped organize the massive career expo that awaited candidates just inside those glass front doors.
