I just graduated from college, and I'm looking for a job at a bank or credit union. My fraternity brothers and I stay on touch through Facebook. Now that I'm hoping to enter the professional world, I try to keep my posts clean, but my friends don't have the same approach. There are photos of us drinking, playing pranks on each other, and partying, and I'm tagged in a lot of them. But it's typical college stuff. Is this something potential employers consider in hiring? Are they legally allowed to look at social media sites for information on applicants?
