As a Social Media Specialist, you will be responsible for planning and executing campaigns, so you must provide some insight into the social media campaign you managed and what was your approach. Smart candidates should be able to articulate the issues they experienced and how they handled them.
In terms of their approach, what were the goals, what methods were used to achieve the goals and how they measured their outcome? It is not mandatory that the campaign was a huge success, as far as the approach was correct.
