This seems like terrible advice to me. "Men with daughters are less sexist" and "Men whose wives work are more sympathetic to working mothers" are extremely vague, only loosely correlated to what you want to know, and pure anecdata. Someone could make up an equally plausible counter-argument (say, "men with young daughters are more likely to infantilize female coworkers"), but it would still just be story-telling.

If you want to know how your possible-future boss treats the women he works with, how about, "Have you had any women report to you? How'd that work out? Were there conflicts, and if so, how did you resolve them? Do you think they'd be happy to work for you again?" I'd be happy to answer those questions. Asking what my wife does for a living will get you a very awkward, "Er, let's get back to the interview."

I will happily acknowledge all of your criticisms, since I agree with them.

But I'll also point out a big problem with your suggested other questions: employers know that this is a hot-button issue for some prospective employees, and they will adjust their answers accordingly. There is a right answer when a female interviewee asks "Would your previous female reports be happy to work for you again?" - could you imagine anyone answering "No, actually they hate my guts"? And so the only way to get accurate information is to either ask indirect questions, or to ask them to indirect people (eg. finding other women who have worked for this person and asking them what they thought, which is suggested elsewhere in the thread).

Same reason that no sane employer gives interviews that consist of asking "Do you think you're a good employee?", and only slightly better is "Tell me why I should hire you" or "Tell me about your biggest weakness". Sure, you'll get an answer, but it's very likely to be a.) predictable and b.) not highly correlated with how you eventually evaluate their job performance.

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.

Again, I don't disagree with you. I will never be in a situation like the OP is asking for, because I'm male and so "how will my manager treat women?" is not a question that is professionally relevant to me. When I do interview employers, my procedure is largely as you suggest, except focused on engineering practices, capital structure, runway, and the specific role I'll be fulfilling in the company.

But I'll point out that what you're actually building, with the procedure you suggest, is a mental model of how a candidate is likely to perform in a role, given the information that you can find out about them. It is still a model, and you make a number of assumptions in it (notably, that past performance may predict future results, and that a candidate's description of how they handled a project is actually how they handled it, and that information about how they handled it is more predictive than asking them to do a shortened project in front of you). Some of those assumptions I'd agree with, some of them I wouldn't. My point is that these two questions are ones that a couple different women I know have found predictive of how a manager will treat them, and that these women are fairly high-up in their careers and generally satisfied with them. They are not necessarily the questions I would use, but because I will never be in the situation that they or the OP is in, they are probably a lot more relevant to the OP's situation than any mental models I use.
