Fewer than 10 employees... those interviewing likely know the answers and will share.
Between 10-50 employees... those interviewing may still know the answers and may still be open to sharing them.
Above 50 employees... it is increasingly likely that this information isn't known by more than a few people (those involved in the fundraising, accounts, senior leadership), and that your interviewers do not know it - if they know it at one point in time it's out of date quickly (next raise). It quick becomes something that only a very few people know and the information isn't useful/constructive to those focusing on execution (those who will be interviewing you).
The questions are good... but if you don't get answers and would choose not to take the roles on that basis, then you might want to chat to a lot of people who have been early stage and done well - because very few got answers to those questions.
