Ultimately, you want to try to strike a balance between including experience that is both timely and relevant. There are several basic types of resumes used to apply for job openings. Before you spend time writing up all the details around each position you’ve had, you should decide what style of resume to use, as that can affect how you describe, organize, and list your experience, education, skills, qualifications, and other credentials for employment.
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.
