One of the biggest mistakes you can make when applying to jobs is sending the same generic resume out for each one. Sure, you can apply to more jobs if you don’t take the time to personalize your resume each time, but chances are you won’t get interviews from any of them. If you take the time to tailor your resume, even though you’ll be applying for fewer jobs, you’ll get more interviews.
For example, if you took a job and only stayed there for a month or so, you wouldn’t want to include that position. If you’ve been out of college for more than five years, it’s generally best to remove any internships you’ve had, assuming you have other professional work experience to fill the gap.
