Check your privacy settings
Facebook is constantly changing its privacy settings, so even if your profile was protected in the past, you should check your account settings frequently to make sure it’s not viewable by people you may not want to access it. You may also want to separate your Facebook friends into different groups (such as professional and personal) so you can control how much of your profile they can see.
Know your rights
Some states have enacted legislation to protect you from potential employers (or current ones) who may try to strong arm you into giving up your Facebook username and password. Currently six states prohibit this type of behavior: California, Delaware, Illinois, Maryland, Michigan and New Jersey.
Keep it professional
Above all, it’s important to keep your personal Facebook profile professional. This may seem like an unnecessary hassle, but it’s the best way to ensure that your social media life doesn’t get in the way of you scoring a great job. A good rule of thumb is to not post anything you would be embarrassed to show your grandparents. If it would be awkward to explain that party photo to them, it’ll be just as uncomfortable explaining it to an employer. Don’t give them a reason to doubt your professionalism.
