It’s always a bad idea to use ‘clip art’ in a resume. Many of Amazon.com’s books on resume writing have sample resumes that use clip art. And despite these books being very well-written and generally excellent resources for resume writers, I find their decision to use ‘clip art’ appalling.
Clip art is by its nature fun, simplistic and cartoony. A resume is a document that is trying to build a professional image where neither person (hiring manager or job applicant) is familiar with each other. There is a disconnect between ‘professional’ and ‘clip art’ and it’s as wide as the grand canyon.
I found this image in a resume book that I’ve used as reference – I still think it’s an excellent book for writing an excellent resume, however I question what value the decision to use clip art adds (forgive the poor quality):
