The cost is too good to be true. It is only human to try to find the best service at an affordable price. However it is also true that you get what you pay for. If a service says that it can write your resume for a few dollars it is better to be cautious. Creating good quality resumes requires using specific skills. The cost can be lower only if the summary of your career is part of a mass produced set of similar documents.
There are millions of resumes being uploaded to job sites and because of this job sites have an ongoing need for more and more web servers. Job sites earn revenue from recruiters and employers that are subscribers and not from job seekers so it makes sense to eliminate this cost and pass it on to the resume website provider. Since people manage multiple resumes in their profiles to apply for different jobs it would be better for everyone if job seekers had multiple links to different resume pages instead of resume PDFs. The storage cost to job sites is eliminated and job sites can reduce their fees to subscribers.
Mass production may be suitable for nuts and bolts; however it sure is not the right method to create your resume. This is what the resume mills or factories do - produce resumes that all look the same. When a prospective employer receives hundreds of applications and your resume is similar to the majority of them the impression created is not good enough to warrant an interview. Most likely it will not even be viewed.
Add in a list of skills Your resume is no place for modesty. Highlight your skills especially if they are specific to the job youre applying for and list where you gained experience with that skill set. Instead of being general give concrete details and highlights. For example list your experience with Microsoft Office or even a particular piece of software over computer skills. Make sure to include plenty of competency statements.
Tailor the resume to the job description Make sure that every time you apply for a job that you adjust your resume to the particular place you are applying. Read through the job description and make notes of any areas being focused on. Make sure to add information to your resume that highlights your abilities in those areas and makes you more attractive for the particular position you are applying for.
