Yeah, but hiring is a big series of assumptions. Resumes and interviews only give you so much confidence on how a person will actually do in the job.
Speaking for myself, I want to hire quickly. I get 10 resumes for 1 spot, I'm not going to agonize over whether the PhD is having a mid-life change and really wants the fast food job, or if they are going to split in a month, or hell, if they have some addiction or personal problem that prevents them from holding a job that matches their qualifications. If there's a candidate that meets the reqs and seems like a fit, I'm moving right along with them.
If the PhD is convincing in an interview that they're really just looking for a switch, sure, but I'm not going to waste a lot of time and energy waiting to be convinced when there are other candidates with a more expected profile also vying for the job.
