If you're asking questions to determine whether the interviewer is suitable for the job of interviewer, then you're pretending to be the HR boss. I can see how that turns people off.

But if you're asking questions to determine if this is a company you might want to work for; you ask them how they work, how they're organized, how they handle specific things, what tools they use, etc, then you're simply doing your job as an interviewee, and I've found it doesn't turn anyone off; they just think I'm well prepared and honestly interested in the job.
