Put your best foot forward/fake it till you make it kind of... you don't need to showcase the side of yourself that eats a pint of Ben and Jerrys and plays slither.io on the couch for 5 hours a night. Show off the hardworking, talented and creative side.
It's cheesy but this PR/branding stuff does work. I used to work with this hack nurse who hired a PR agency and he either wrote or hired someone to ghostwrite all these blog articles about emergency medicine. Suddenly he was getting featured in magazines as "expert nurse Blah RN" and was also getting featured in various "Top Healthcare Provider" type lists and being flown around and getting paid to speak at conferences.
It was kind of annoying because he was pretty clueless when it came to actual patient care and was also a sleazeball who sexually assaulted about 40% of our female workforce. But he had great branding and PR! If you googled him you'd think he was super smart and very impressive.
My point being, sleazeballs like that have absolutely no qualms about outright fabrications, inflating their credentials and lying, so you shouldn't feel guilty about showcasing your most professional, smartest "authentic" self.
