Applying for a job alone isn’t enough because a dozen other candidates are applying for the same position. What does it mean for you? You have to make sure that your application doesn’t get lost among the dozen others – you have to make it stand out. How do you do that? Of course, your resume has to be exceptionally good, but an exceptional resume alone may not be enough. If you are really serious about being called for the interview, a cover letter will improve your chances significantly. It doesn’t matter if it’s required or not – you are better off sending your application with a cover letter than sending it without one. If you know how to write one, that’s great. But, if you don’t, you have to learn, and if you don’t have time to learn, then hire a professional cover letter service . Just don’t apply without one – that is, if you really want that job.
