9. Don't be overly friendly Up until your graduation, you had quite a bit of freedom with how you could interact on social networking sites. But once you enter the job market, that changes. No longer should you think of your social media connections as your online 'friends'; now you have to think of them as potential professional connections. And that will likely mean changing the style in which you communicate. For example, just because a potential employer responds to you using informal language in a Facebook post or via Twitter, does not give you the go-ahead to do the same. It is never okay to use texting shorthand such as LOL or TTYL in any communication with potential employers, no matter how informal your contact at the company is with you. "Remember, just because your immediate contact has no problem sending informal emails to potential employees, doesn't mean that his boss won't mind it," Kuzmeski points out. "Other people at the company might be reading those emails. And for that reason, you should stay professional at all times."
