Demonstrate Your Qualifications

It is one thing to say that you are "hardworking" but it is another to showcase why you are "hardworking".  It is one thing to say you are "highly qualified" but can you support that statement.  Can you showcase examples of collaboration / teamwork in your resume as opposed to making a blanket statement about your ability to work with others.

In short, you can make all the lofty statements you want but your resume is where you need to provide specific examples of your qualifications and attributes.  If your resume is void of examples, it is time to revamp your resume.
