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.
Some of the templates are specific to given industries. You can find those that are appropriate for academics and many others to suit the needs you have. You can download resume templates to suit the number of applications you need to make, one different from the other. You don't have to start all over again when applying for a different kind of job or in a different sector. This is a big benefit especially for fresh graduates trying their luck in different sectors and job capacities. The templates give you an easy time getting everything together.
