Dear Mrs Benson,
I am writing this letter to to apply for staff to your bookshop. Incidentally, I see your advertisement in a newspaper and then I write a letter of application immediately. I think this opportunity is an excellent match to my qualifications and experience.
I really enjoy reading books. I am not a nerd but reading is my little hobby. I like science books, novels, detective books... And those books are in your bookshop. It is a good environment for me. About speaking English, I can not speak like a native English speaker, but I can speak English with basic communication. More importantly, I have some strong work experience that will help me with this job if I am successful. I used to be a multi-level marketing agent for the Body Shop, and I also used to sell online. With all that experience, I look forward to hearing from you soon.
Sincerely,
Ngoc Duong
