What that means that you overqualified for a job.

In addition to the problem of employees jumping ship as soon as something better comes along overqualified individuals are often bored and frustrated.

Due to the IS/IT employment market we have computer operators with bachelors degrees in business administration or computer science. They took entry level positions because it was all they could find. In general they they are bored and probably ask themself, “I studied 4 years and took out student loans for this?”

Unhappy employees are rarely good employees even if they stick around.

Usually if an prospective employer tells an interviewee, “Your overqualified for this job”, it means that your education or experience is so far beyond that of the typical person holding the job that they don’t think you’ll stay in the job because you won’t be satisfied with it. Right or wrong, that’s probably what they are thinking. They might even wonder why you are applying for a job that is beneath what they think is appropriate for you.
