Platinum Group Security interview questions

Initial interview at Platinum office in Doral. Questions were basic. Was told to go to a building in Aventura to interview with site manager that everything was set up for Thursday at 10am. Thursday I arrive at 9.50am and tell the guy at the desk I was there to interview with the manager. He goes into the office, comes back and says...are you sure this is the place? manager has no interviews scheduled for today or tomorrow. I asked him to please check again. Came back empty handed. He then told me he was going to call the office to find out. At this time, and seeing the lack of seriousness, I told the guy forget it and left. As I was getting in my car, the office called and said there had been a mistake, I then told them, "look, we haven't started our working relationship yet and this show of ineptitude happens?forget it, I already can't trust you"
