While many college-student resumes are one page, you don't
absolutely have to have a one-page resume, especially if you have
good experience. Your resume should be long enough to establish what
you have to offer, yet short enough to entice the reader to want to know more (interview).
All important points should be introduced on the first page if
your resume is more than one page.
If the material on the second page of your resume fills less
than half a page, it may be better to condense to one page.
Your resume shouldn't be more than two pages, without a good reason. (But, again, for
more experienced job-seekers, even this rule can be broken.)
Your resume type size should be no smaller than 10-12 point. Eleven-point type is ideal.
Include only relevant (to the job you are seeking) information on your resume.
