Dear Sir/Madam,
I am interested in the position available with your respected company. I believe that I can make a substantial contribution to your Administration staff and the office environment.
The ability to be flexible and adapt to new situations is an integral part of my previous position as an executive and customer service representative. I can handle all aspects of network administrator and troubleshooter work efficiently based on my previous experience, my language skills and computer knowledge.
A career with your respected firm would be especially appealing to me. It would enable me to combine my administrative skills and computer knowledge with my good command of the English language.
