I worked with a PWM at a previous job where I had the opportunity to see his resume. (I was asked to review the whole team's for proofreading purposes). This guy totally inflated his accomplishments, took credit for work I and others did, and even went so far as to proclaim his skill at team building, when even the folks he was friends with on the team thought he was a PITA diva. Claimed to be a software developer because he could build Drupal sites. Ever since then, I stopped understating my accomplishments. (I've always negotiated higher salaries from way back when).
