The job search can be tiring but you can help yourself out by taking extra steps during the application process. One key factor is to make sure your cover letter complements your CV.
Most job openings and descriptions request for your cover letter as part of the application. A well-written cover letter is great but a cover letter that complements your CV is the best!
Read through the job description, ensure that the details on your CV and content of your cover letter fit into the expected capabilities as indicated in the opening.
Ensure that your CV is reflected in your cover letter, so that the person looking through your application can be convinced that you are aware of your capability and willingness to work.
