All it takes is just one person in the first spot in her listing of jobs on her resume to fail to properly vet her. Once you start having job experience, people don't look as hard at your resume. Nobody wants to do all the legwork verifying transcripts and calling up references, they just assume someone else down the line did the work. The resume looks impressive but she's not claiming a Harvard doctorate so it doesn't sound totally incredible. I laugh that they can't even find records of her getting a bachelor's. That's when you know someone at her first job was either very lazy to not even verify her or she got in because she knew someone and they didn't bother to check anything.
