When you should include covering letters
* When sending your CV to recruitment agencies (you have to let them know what kind of work you are looking for).
* When enquiring about possible job vacancies with an employer.
* When applying for advertised jobs that request you send your CV to the employer.
Applying for advertised jobs
When applying for advertised jobs, your covering letters should, again, state why you are the best person for the job, relating the information in the job description to your experience and skills.
You should make special note of what the requirements are in the job specification and reflect this in your CV.
Your covering letter, however, should be brief, professional and be directed to person stated on the job advert. At the end of the day, the employer is only going to look at CV’s in this case.
