Be specific; recruiters are waiting for you to make them a proposal. They must be able to easily pinpoint your skills, e.g. drawing up financial statements, balancing accounts, reconciling the bank balance, calculating and preparing payroll, preparing cheques and salary deductions forms.
It is no longer necessary to send a cover letter along with your CV. Do so only if you deem it appropriate; the best thing is then to send it in the body of your e-mail with your CV as an attachment.
The first interview generally takes place with human resources. It gives the interviewers a chance to study your personality and to get a feel for who you are. Your relationship and interpersonal skills, and also your motivation, will be examined. To prepare for the interview, you should get to know yourself thoroughly.
