In addition to the more established grad schemes, there have been two other internship roles that I've been told about.
The first is from Quirk. They need a few interns for some social media work. Their clients are Warner Bros, Investec, SAB Miller, Nando's...to name a few. If this sounds like your cup of tea, email Tom at email@example.com.
The second is from Lambie Nairn, who are looking for a full time intern to start in February 2011 to support the marketing, communications and new business team. Activities will include processing weekly business development reports, research and analysis of sectors, monitoring of press for client teams and general administrative support.
They are after someone with a positive flexible attitude, strong attention to detail and most importantly, someone who is an excellent communicator. The internship would be on a rolling monthly basis; people who are doing a year in industry are welcome, but as it's a full-time position applicants must be able to do a full working week.
Applicants will need to send a CV and covering letter to firstname.lastname@example.org with the subject header "Internship 2011".
Best of luck with those two.
