The term purple squirrel candidate is used by recruiters to describe the ideal applicant for a job opening. Purple squirrels will match all of the employer's requirements, including qualifications, education, skills, and work experience.
When a job applicant is thought to exactly match the employer's requirements, the recruiter may refer to the candidate as a "purple squirrel." The term refers to the rarity of the find; it's extremely unusual to discover an exact match.
A purple squirrel will meet the employer's job requirements in every facet, including the right level of education, prior work experience, and skillset. This type of candidate is prized by employers because, in theory, they can handle all of the roles and responsibilities of the job opening and have an immediate impact on the overall effectiveness of the company's operations.
