I walked in about 25 minutes early, it's a huge corporate campus in Las Colinas (Irving), Texas. You can (and will) get lost in the building if you are not escorted. My interview was at 1:00 P.M., the Human Resources recruiter did not call me in until 1:20 P.M. After complaining about her job and gossiping for about twenty minutes, she finally walked me over to the hiring managers. I was interviewed by two individuals, both of with seemed bored.
