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.
It is much easier to update your resume periodically than all at once, so even when you’re employed, set a reminder to refresh your resume every three months, while the information is still fresh in your head. This will make your next job search much easier, should you decide to switch companies or careers in the future.
