On the heels of Campbell Mithun’s tweet-for-your-internship competition this winter, another Minneapolis ad shop issues a show-us-your-new-media-affinity call for applications. Olson tells intern candidates “Apply by phone. Please, no calls.” The rules? “Make something cool, meaty, beautiful using only a phone,” then post it on line and send Olson the link (plus a cover letter and resumé). To see applicants’ work and Olson’s own made-by-phone video, check out olsonoterns.com.
