I believe I am fully qualified for the work you described. My experience with ABC Corporation is directly related to the work you are offering. Also, my academic background and the training I received as an administrative assistant provide a strong base for further development.
Thanks again for the interview. I look forward to hearing from you soon.
Sincerely yours,
