As an education counselor whose work primarily revolves around technical content writing, should I be offered this opportunity, you'd be hiring someone who's proven at the required skill for 3+ years. As such, quality is certainly something you can stay assured about. More importantly, my work could be categorized as personnel marketing, for which the content that I generate necessarily needs to be appealing to the target reader, you would certainly like to recruit someone who has done that successfully on a consistent basis. I have helped several people build their LinkedIn profiles and achieve noticeably high visibility post the modifications that I made. I am sure you'd want to recruit someone who can be guaranteed to perform.
