Dear Andrew Hall,
Thank you for giving me a chance to have an interview with you last Monday. The interview has proved very informative. I feel that I am much more confident about applying for the Customer Service Representative position. My experience working at STS Center has equipped me with the necessary skills and knowledge needed for this job. I am excited with the thought of working for you. I have heard so many great things about your company and I would be very happy to be a part of your wonderful staff. I hope you will give me an opportunity to work for you. I hope to hear from you soon.
