There are some things that don’t belong on a resume for a job. What you exclude is just as important as what you include. Ideally, your resume should reflect experience that is relevant to the job you are applying to, and typically no more than ten to fifteen years in the past. Since your resume should, if possible, be no longer than one or two pages, you may need to nix certain items.
Soft Skills. Soft skills are any skills that are not provable or quantifiable. If Sarah Smith says she is “hardworking”, “problem solving”, has a “strong work ethic”, and “positive attitude”, the recruiter has no way of knowing whether or not that is true. Use hard skills and prove your soft skills by listing your previous accomplishments and promotions on your resume.
