CHICAGO (AdAge.com) — The number 13 is often said to be bad luck. But not for a group of interns chosen by Campbell Mithun, Minneapolis, which announced today it will hire its group of summer 2011 interns based on an application consisting of 13 tweets sent between Feb. 13 and Feb. 25.

I love that Cambell Mithun will choose their Minneapolis summer interns based on a series of 13 Tweets. How better for students to not only show what they know, but to do it in the process of getting a job.
