the most important aspect i've learned about writing a resume and even a cover letter for a potential job is to seem as genuine about yourself as possible. i was always told that you want them to want you even if you're not so sure you want them. i feel like some people either take this to the extreme or don't follow it at all.
i know a few people that are so worried about how they are portrayed on the internet that they detag almost all photos on facebook, just in case a professional contact happens to stumble upon their profile. they are so worried that they don't even let their personality show through in the interests and activities section where they are the only ones in control of what is written. no matter how much i think about it i cannot relate to these people, so much so that i've questioned a hundred times over what the difference is between professional and personal contacts. obviously there has been a difference, but in my reality i believe anyone can become a professional contact in some way or another. because of the evolution of social media and websites such as LinkedIn, it has become so much easier to advance your career through family and friends (which to my understanding are traditionally classified as personal contacts) than in the past.
but then there are the ones that don't hold any standards on the internet at all. in my experience i've noticed that younger generations more so than older ones, are those with no sense of professional behavior. my brother is 18 and some of the girls he has gone to high school with have posted many blogs and pictures that i would never even want family and friends who have known my personality for years to see. posting these types of things dilutes the actual personality that these people might have and leaves little up to the imagination.
branding yourself through social media can be difficult for some and requires a bit of work for others but i think that if you try too hard to control things you seem too clean and disingenuous. but on the other hand if you need some type of control and act otherwise there are obviously going to be consequences.
..and just for fun i'd love to be around when those kids try to get jobs in the real world
