That sounds to me like someone who doesn't want to be stepped all over in the name of having a career, and it also sounds like you're impatiently skipping over people while also paradoxically expecting to understand everything about who they are from a singular and very limited interaction.
During a job interview, you evidently see people as an abstract mesh of characteristics that you believe you can deduce their entire identity from, and similarly they mostly see you as a mere abstract mechanism of the company. I'm sure that such a candidate would be happy to answer more personal questions over a stress-free cup of coffee, feeling like they're chatting with a person instead of having to win over a corporate proxy.
I don't think anyone goes to a job interview expecting to be applying for friendship with the interviewer, but to have their relevant skills evaluated first and foremost. It's perfectly normal to find anything else extremely weird and needlessly intrusive and to reserve one's right to privacy and go look for another, saner workplace.
It's just about the same issue as with chat control. You also haven't addressed my other points, so I assume that what you actually value in the workforce is half-truths and facades.
It's your rightful choice, and it leaves me with my assumptions, but I just ask that you remember that this is still a casual conversation that we're having, and that I have no ulterior motives, and that my questions were on topic and driven by genuine curiosity in your way of thinking instead of a need to tick boxes. I don't know any side of you other than the one you're currently showing me; however, I understand that it most likely does not reflect the better part who you really are.
