Make your resume original Make sure your resume stands out from the crowd. Dont be afraid of trying something different or breaking from the mold. Sometimes a little creativity can garner enough attention to get your resume read which can make all the difference. Dont overdo it though. Being wacky or silly may be a part of your personality but usually is not a desirable quality in the work place. Photos are usually a bad idea as well. Be creative but keep it simple to avoid drawing attention away from what is really important.
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.
