I found this related question on WPSE, but my question is slightly different.
Not too long ago I had two telephone interviews with two different companies and on both occasions the interviewer asked if I had any questions. Both times I asked them to elaborate on the technology I would be using (both job postings were vague) and they were unable to answer. I didn't end up getting either job, but it made me wonder, can it reflect poorly on me to ask a question the interviewer is unable to answer?
My intention was never to ask a question I knew they didn't know. I can only assume the answers I give to the questions they ask are being documented for review later, including all questions I ask the interviewer. Is it possible that they removed me from consideration because they didn't want to document that I asked a question they couldn't answer because it would reflect poorly on them?
