High quality questions say something about you. Low quality questions do too. Would you ever hire someone whose question is like "so, do a lot of hotties work here?" Probably not, because ... what kind of person is this? Similarly, if the person who doesn't have an offer and doesn't know much about the role is hyper-focused on their time-off, something is off too. PTO is important, it's just a thing you need to be thinking about once you have an offer and think the job is otherwise a match, not as like the #1 question.
