These all seem like the basic questions I'd be asking during any interview - with the exception of runway, because I don't like startup culture (though if I were applying I sure as hell would be checking this) - and I don't think I'm significantly different from people I've interviewed.

I'm not sure why this guy's experience is so different from mine? I assume it's related to hiring/recruitment orientation (more junior/inexperienced folk?). The big one I could imagine is people failing to ask the "will the company still exist in 6 months?" question due to a default assumption that companies don't die?
