The cover letter is not the only the document necessary for any job search. It is also claimed and / or recommended for:
- integrate certain schools or universities
- obtain access to certain courses
- support a recommendation or cooptation
In some cases the cover letter may be sent alone when sending a CV alone is a very inefficient method. It's always a CV that is attached to the letter and
not the reverse!
For free applications the cover letter alone can convince your partner to meet you...
Therefore, this letter should be particularly careful both in its form and its contents...
