The number one tip in our Resume Writing Guide is to keep your resume as clear and to-the-point as possible. While there is no official length limit to your resume, it is meant to showcase only your relevant work experience as fast as possible. The average time spent looking at a resume is 6 seconds, so a concise resume in a one page format is highly preferred. The key word in resume writing is relevant. For example, if an early part of your employment history does not pertain to the job for which you’re applying, and you’re running out of space, don’t include that information.
However, this is a case where you’ll want to use your common sense. If you went to college for marketing and had a marketing internship your senior year, then worked as a server for the next several years, you would want to include your marketing internship.
