Employer or Recruiter says overqualified and you say experienced.
why wouldnt a company want to hire someone with more experie-
nce and skills, an employer may be refused to recruite an applicant
with a lenghtly resume and extensive credentials will grow restless in a position that is not challenging,or they may be concer-ned that the applicant is just looking for something to pass the time untill a better job comes along.
If an employer expresses fear that you will leave once you find a better job , point to your past employment record ,also you can offer to sign an employment contract.
An employer may also be worried that they cant pay your desired salary,if so consider lowering your salary requirement .
You can point out , how you may have cut costs at your previous jobs, if its true.
