Purple squirrel is a term used by employment recruiters to describe a job candidate with precisely the right education, experience, and qualifications that perfectly fits a job’s multifaceted requirements. In theory, this prized “purple squirrel” could immediately handle all the expansive variety of responsibilities of a job description with no training and would allow businesses to function with fewer workers.

The book purports to focus on "the art and science of getting recruited" and has been a best-seller in multiple job search and career categories on Amazon.com.
