Do watch your grammar

"Many job seekers think that [recruiters] use social media to see what they look like and to see what their friends look like. Personally, I could care less about what you look like, but I do care about what you sound like," says top recruiter Abby Kohut. "Using poor language or speaking badly about people or constantly complaining will not win you any points with recruiters."

Kohut adds, even when using abbreviations, check your grammar and spelling to make sure that it's top notch.
