The first thing that you should consider is using the keywords that are contained in the job description of the job that you are applying for.
Besides that, you should also strive to make your Resume writing service short, typically 2–3 pages so that it does not seem as if you are lying or trying to cook up your story to get the job.
The last would be to write a very compelling cover letter that highlights your previous jobs, internships you did, volunteer work and what you achieved, and how they relate to the job you are applying for.
