Are you prepared to answer some of these tough questions-Social Media Recruiter

I am just wondering if tomorrow I get an interview for this position then what would be the toughest questions for a Social Media Recruiter,after some brain storming some of them would be:-

• How familiar are you with social networks, blogs, and online communities. Which ones are you currently a part of, and have you ever used them to recruit?
• What is the purpose of social media in recruitment?
• Tell us about some of the challenges you have faced when introducing social media in your job, and how you overcame them?
• Which sites are you most comfortable with and why?
• How do you measure your success in social media? How would you justify it?
• Is it important that a company should engage its recruitment team in social media to be successful.
• Assume that I know very little about social media, convince me that I personally should use social media as a recruitment tool in 2 minutes or less.

All the best to we recruiters! Please share some of your views.
