Having more education, skills, or experience than what is needed for a specific job or position.

Overqualified → It is formed from "over-" (meaning excessively) and "qualified" (from Latin "qualificare", meaning to make fit or to qualify). The word "overqualified" means having qualifications that exceed what is necessary for a particular job or role.
Think of being 'excessively' ('over-') 'fit' or 'qualified' for a job — that's why overqualified means having more qualifications than needed.
