A web and social media consultant's scope of work includes extensive industry knowledge. You are not out there to entertain people with your witty personality. Your job is to represent the company, project the corporate image, and interface directly with the public about the company. Interjecting charm and personality is certainly a plus, it's just not the primary focus. Your follower count does not matter. It's not about you. To land the job, convince the hiring manager that you can understand the company and its objectives and convey a positive image of the company. You have to have the ability to not only project, but also to listen…to consumers, market experts, prospects and management, and use the knowledge gleaned to enrich your own catalogue of response.
