via Fill Out a Thin Resume by Scanning Through Job Postings:
"If you feel like your resume could use some padding, fear not, you’re probably just selling yourself short. A little job posting exploration can help you find some skills you forgot to add.
It’s hard to be objective and write about yourself when you’re putting together a resume. You can easily forget things you’re skilled at because they’ve become second nature to you. That’s why Rita Friedman, a Philadelphia-based career coach, suggests you scan through a bunch of job postings and look at the required skills. Friedman recommends you specifically highlight the parts that make you say “Oh, I do that all the time!” There are probably at least a few things you forgot about. And while you’re scanning, you can also take note of the important job skills you haven’t acquired yet. That way you know what to work on for the future."
