Using a template could also mean that the resume is written correctly. There are certain fonts and styles which have to be adhered to when writing a resume. With a template, you will know that you have used the correct requirements and your mind will be at ease. These templates are designed mostly by professionals and they know the importance of having plenty of white space and bullet point format for providing information. You should not try to reduce such space or avoid the use of bullet points. This will take away the layout benefits which a professional template will bring to your resume.
Beyond just ensuring that your resume looks like all the other resumes out there, templates are also generated as "one_size_fits_all" solutions. Do your career, your unique work experience, and your individual goals really fit in a one_size_fits_all format? For the vast majority of people, the answer will be no. Very few professionals have a completely linear, untarnished employment history. If there are any 'problems' in your background__such as a period of unemployment, too frequent job changes, a demotion, or any number of other challenges__a resume template will only accentuate and call attention to the negatives.
