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.
For example, if you took a job and only stayed there for a month or so, you wouldn’t want to include that position. If you’ve been out of college for more than five years, it’s generally best to remove any internships you’ve had, assuming you have other professional work experience to fill the gap.
