Please give me an example of application letter of service crew.
All application letters are basically quite similar. If you click here you will find a sample (you have to scroll down the page a while to find it.) You should begin by explaining which job you want and where you saw it advertised. Then refer to your CV, mentioning your qualifications and experience. The third paragraph should explain why, as a character, you are suited to this job. There are also additional letter writing tips on the page I gave you, so it's worth exploring.
An application letter should state why you are interested in a particular job i.e. Crew in Fast Food Preparation and should then indicate clearly what qualifications you have that make you suitable for the particular position. The detail of your application letter will depend on whether you are asked to also submit a CV/Resume along with it. If you are NOT asked to, then your letter should go into detail that includes: Previous jobs and your responsibilities there, your superior's name and contact details, possibly salary, and your reason for leaving. If you are asked to include a CV/Resume, then you can simply detail your primary list of skills.
