Nowadays, social media platforms such as Facebook that contain absurd amounts of personal information on its users have completely changed the meaning and confidentiality of private information. There are many consequences and disadvantages that have arose due to the increasing accessibility of people’s personal information. One of the biggest problems caused by this arises during teen job interviews. Many teens are mindlessly displaying photos, videos and statuses that show them taking part in unprofessional and inappropriate activities. Prior to this over-exposure of users’ privacies, an employer had no way of obtaining information about the personal life of the individual being interviewed. However, with the help of social media like Facebook, interviewers can learn a lot about an individual’s private and social life before the interview ever takes place. In many cases, this results in the interviewer stumbling upon an undesired picture or status. This will often cause the interviewer to either form a strong bias against the individual and thus decreasing his or her chances of getting the job desired, or to simply never consider the individual for an interview. In both cases, the person being interviewed is suffering from detrimental consequences even though the “undesired content” on his or her Facebook profile may have been a mistake and does not represent the person’s personal nor social life. This causes many employers to miss out on potential skillful employees solely due to an irrelevant Facebook picture or post.
