Got a call from a guy claiming he was from a job agency which was perfect since I was looking for a job at the time. First red flag went off when it seemed like the person wasn't really interested in some of my responses and went "great!" right away with no follow up. First question was year I finished high school, then zip code, and then asked for my first and last name which I thought was strange that they didn't have my name. At that point I started mentioning I'll call them back when I need a job and they promptly hung up without saying anything.
