Object : Application for a programming internship at Agilent Technologies. From April – August 2007

Dear Sir,

I heard about Agilent Technologies performances at school as I am a student in telecommunication systems. I would be very interested to know whether or not you have any vacancies for an internship during the months given above.
Your offer for an internship extremely interests me as it seems to be a very unique experience and opportunity to get involved in such a fast growing and well known company. What attracts me even more is the wide range of jobs and tasks that your company gives to the intern along with the great amount of responsibility granted upon them. I also have a great interest in information technology and programming.
With the great reputation that your company has made for itself over the years along with the strong entrepreneurial culture and technological knowledge, I am sure that this internship would be an incredible opportunity for me to be a part of your team of professionals and a great way to share our passion in this field.
I have quite a wide range of skills that have been developed during past internships as well as various activities at university. They include the experience of working with a team of renowned professionals and learning from them, strong quantitative and analytical skills and a passion and strong commitment for my work.
I appreciate the time you have taken to read and review my resume and I wait to hear from you at your earliest convenience. I hope to meet you soon to discuss my application.
Sincerely,
