Most people use a cover letter to do nothing more than announce that they have enclosed their CV! This is a wasted opportunity. A cover letter should create a sense of anticipation for the reader, and leave them keen to read the CV.
When you apply for this service, you simply upload your CV, provide
us with complete details of the role you are applying for (as worded
in the advertisement), along with the name and address of the company
and the person you want the letter addressed to.
