An interview is a fairly terrible way to get to know a company's culture. Among other things, the interview is a filter, not an employment conversation.
I have seen this from both sides, and it is something you _need_ to know if you are interviewing people. The very best people for the job will have options. The very best hires don't _need_ your job. Not considering that your organization is being evaluated by the same folks you want to hire is not smart.
... I HAVE PEOPLE SKILLS, DAMMIT!!!
