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.
You should also include information about promotions in this section. When listing your responsibilities, start with the most valuable experience first, since the employer will likely be skimming your resume top-down.
