If you are being inauthentic you just might be. In other words, are you really who you say you are? In the age of social media it is fairly common for people to showcase a polished version of themselves online. The problem with that is if the person you have presented as being on LinkedIn, Twitter, Facebook etc is not who the employer see during the interview you will come across as inauthentic.
The way to combat this is to be realistic in what you share. When you are working on professional platforms like LinkedIn or are writing your resume, be sure to be honest about your skills and experiences. You of course want to put yourself in the best light possible, just don’t overdo it. When on more informal social media site, just be authentically you. If you’re consistently represented across all social media platforms then people won’t see contradictions in your language, passions, history and interest in your field.
