Your goal should be to write your resume with both robots and humans in mind. Many organizations use Applicant Tracking Systems to sort and vet resumes, before hiring managers ever take a look at them. This means that you could have the best experience and qualifications in a whole field of candidates, and a pretty decent resume besides, but your information will fall through the cracks if your resume doesn’t contain the right keywords. Good keywords will refer not only to your experience but to the job description in the posting as well.
Only include your GPA if it is higher than 3.5 on a 4 point scale (no need to mention that 2.0 when you moved into the frat house sophomore year) and only if you are a recent graudate. There are a few exceptions to this rule, like if you’re applying for a job in academia or engineering where a GPA is expected. You can also list honors or awards if you’re a recent graduate. If you attended college, but did not finish your degree, list the number of credits obtained. For recent graduates, education and internship are your main selling point. But if you’ve already been in the workforce, tone down your education section, the best rule of thumb is that one line will suffice.
