Have you done many interviews? The solution to "people lie sometimes" is not to rely on correlation-to-a-correlation Ouija board bullshit, it's to delve and ask for more detail until you're satisfied the person isn't bullshitting. I want to know if candidates are smart and hard-working; I don't ask them "Are you smart and hard-working", and I don't ask them what their spouse does for a living based on some cockamamie theory about how that relates to anything. I ask them to describe a project they worked on and their role in it and how it went, and I keep asking supporting questions and follow-ups until I'm pretty sure I know whether I want to hire them or not.
Candidates need to do the same thing: delve, ask for details, and keep going until they're satisfied that they know whether this is a job they want. I think those questions I posted are a good way to do that. If OP asks those questions, and then asks follow-ups, until she's pretty well convinced that this is/isn't someone she wants to work for, my suspicion is she'll very likely be right.
