I applied through an employee referral. The process took 1+ week. I interviewed at Georgia Tech (Atlanta Downtown Post Office, GA) in May 2013
Interview
The interview process was fairly smooth in the sense that I became aware of the position and was hired in less than two weeks. The process includes sending you basic information and having a conversation with the office manager. If everything goes well she will hire you. Make sure to talk about family, goals and aspiration.
