Excellent Question! I believe "Social Media" should be added to the "Specialties" of this question.
However, I don't believe you could find "best" questions, neither could you expect certain "best" answers from a candidate. I will try to add my takes (with no certain order)
- How do you measure the success of a certain page/account ?
- If you are to publish a new page/account, what would you do to generate followers ?
- While managing two channels Twitter and Facebook, how would your strategy differ between both ?
