+1 on this answer. Ideally any interviewer intentionally sets aside time to answer your questions. If it's a total one way street that'll tell you something about the company.

In our interview process we have an informal session totally dedicated to answering the candidate's questions about anything. The setup is simple, two of our engineers and the candidate hop on a call (or meet in person) and just talk.

Many of the folks who have accepted our offers refer back to that session as the thing that really sealed the deal for them.
