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.
Functional resumes are good when you have little to zero work experience (or new grads). This type of resume allows you to showcase skills that fit in with the job requirements. Fair warning: most recruiters and hiring managers dont like this format and feel as though you may be hiding something. If you have a chronological resume you do not want to have one part chronological and one part functional because it will throw off the entire formatting and may confuse the employer about your skill set.
Ask yourself - is a cheap resume of any worth if all it does is extending the period of your job search? The answer is simple - no. The cost should not be the sole focus when you choose a resume writing service. The priority should be on the quality of the final product. Only a unique resume that captures the attention of prospective employers and guarantees an interview call is worth your money.
Focus on achievements Employers not only want to know what you have done in the past they also want to know where you have excelled. If you have awards achievements or on the job highlights make sure to add them. If you were part of a team you were part of the success. If your project increased production by 20% and you played a part in it add it on your resume!
Make sure to have contact information on every page Nothing is worse than having an amazing resume and forgetting to add in contact information. Do not assume that if your resume is two pages that they will stay together either. Put your name and contact info at the top of every page and add in page numbers for a more professional look as well.
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.
